Review of the GlobalSat GS-580P bike computer (First posted July- 5-2012 at 07:48 pm)

So far I am very happy with my new GS-580P bike computer.  GS-580P Backlight on I have never used a Garmin Edge 500 but a couple of riders I ride with have them and they are happy with them. From the research I did before jumping into the GS-580P, most of the comments comparing this device with the Garmin were done by people who have not used or even seen the GS-580P in person. If I was considering getting a similar toy I would definitely buy the GlobalSat GS-580P over the Garmin or the Timex; can't go wrong with the GS-580P for the price, features and a company that listen its users. I can live with the not so great user manual, heck prefer a more user friendly manual? Download the Timex Cycle Trainer user manual, seriously, it is a better written manual with easier to understand instructions and believe it or not ALL instructions and information in it apply to the GS-580P. If you are brave you can try flashing the GS-580P with the Timex Clycle trainer firmware to see if that works; in theory it would make the device recognizable by the Timex software that is Mac compatible. I may try that one day when I grow up... but not today. Anyhow me likes my new toy. BTW, to my untrained eye this device is, judging by the online photos and even the screenshots provided in both user manuals, the same as the Timex Cycle Trainer but it seems they have slightly different firmware. I took some screenshots of my unit with random data in each screen just to show the way the fields are organized in the screen depending on how many items you want displayed. My biased first impressions of my GS-580P follow:


 Custom screen with 6 fields  Custom screen with 5 fields  Custom screen with 4 fields  Custom screen with 3 fields  Compass  Track Back

  • Similar form factor to the Garmin Edge 500 and seems to do EVERYTHING the Garmin does for a LOT less money.
  • has a great price for the GS-580P, $167. $216 from Amazon (Amazon's GlobalSat GB-580F has the same features/sensors as the one from they both come with Speed, Cadence and Heart Rate monitor strap and free shipping.
  • The Garmin Edge 500 with similar specs and sensors is $350 at
  • The model I've got, the 580P, comes with a a Speed sensor, a Cadence sensor and a Heart Rate sensor/strap. The Speed sensor is very useful when riding trainers or rollers indoors or when you don't need/want to use the GPS speed information. Actually the Speed sensor probably can provide greater accuracy than the GPS speed data as you don't rely on being able to get a good satellite signal.
  • Can turn off receiving each different sensor data individually to save battery life. If Speed Sensor is off the speed is calculated using the GPS. The GPS signal itself can also be turned off.
  • Can upload a .KML (Google Earth format) file to the unit and then use the trackback function to follow the route backwards or forward. I have used this function many times, on and off road, and works very well. The unit will display a thick grey line with upcoming turns (see screenshot) that is very easy to follow. No map to follow just a line with turns but it works extremely well. Of course this feature works best with accurate GPS tracks. I have used files from online mapping sites like and also tracks created by my own GS-580P and other brands of GPS units.
  • Settings for 5 different bikes.
  • Manufacturer and its team of developers actually listen and consider improvements suggested by owners/users.
  • Can change many settings (but not all) using the included PC software (TrainingGym Pro).
  • Can do a backup of the unit settings to upload latter.
  • Great GPS accuracy and acquires satellite signal relatively fast, about 10-30 seconds on a clear day. At least at my place. Have not had the chance to use it starting at a different location.
  • 4 customizable screens. Each screen can display anywhere from 2, up to 6 fields. A whole lot of data are available. Just to name a few: Distance, Speed, HR, Cadence, Elapsed Time, Slope, Altitude, Temperature, Pressure, Calories, Power, Lap, Pacer (Training partner) and great number of Averages, Max and so on for them (i.e., Average Speed, Max Power, HR in Zone, etc) See table below for listing off all available data for the custom pages fields.
  • Backlight for ease reading riding.
  • Support ANT+ sensors.
  • The Timex Cycle Trainer seems to be the exact same unit (at least on the outside) Accessories should be easy to find.
  • Easy to use during the ride.
  • Claim 18 hr battery life. I have not tested this yet. Charges using a USB cable. The specs list a Voltage of "3.7V for a rechargeable battery" and "5V for charging input" so if I am correct my crapy tiny iPhone wall chager (5V) would work just fine. I wonder if relying on finding a wall electrical outlet (120 0r 220 W) or USB computer port to charge it would be a workable solution during long brevets, probably not but definitely would work on many bicycle touring situations.
  • 6000 Lap history, that is more stuff than what I can remember...
  • 100 Waypoints. This may seem low but I'll need to experiment to see how far 100 waypoints can take me.
  • Built in Barometer for accurate elevation data. Can be turned off to rely on the GPS elevation info if wanted/needed. There is definitely diference between the elevation reported by a GPS signal and a barometer. When I rode to hills that have accurate known elevation on a map the GS-580P, using it barometer, agreed closely with the map.
  • 52416 tracking points. The more often you record points the faster you'll fill up its memory. I set it to record every 3 seconds and it reports I would provide 40 hrs of data records (assuming you have enough battery life) You can set the unit to stop recording when you stop or when you reach a given speed or simply record as long as you decide to start recording.
  • Screen can be rotated to display in Landscape mode. The Bike mount is designed to take advantage of this and the unit can be mounted on the stem or handlebar in either Portrait or Ladscape orientation. Bike mount seems plenty sturdy
  • The overall construction for the device and accesories is a par with any Garmin or Timex device.


  • The included printed manual is bare bones. A more comprehensive user manual in PDF format is included in the CD. However like I noted before the Timex Cycle Trainer manual is better written and all info applies to the GS-580P.
  • No Mac software. I installed the included software, TrainingGym Pro, under a Parallels virtual machine of Windows XP. For now, the only way to access and download/upload data from/to the device is by using Windows software. Mac users will need to to have an installation of Windows under Parallels, VMware Fusion, VM VirtualBox (open Source) or other similar beast. I tried Installing the software using WineBottler a wrapper for Intel Macs of the popular Linux utility Wine but since windows needs a custom driver to see the GS-580P, included in the CD, the program can be installed but it can not communicate with the device :(
  • The product developers are working on a solution for Mac and Linux users and it seems in the short term accessing the 580P as a mass storage USB device, just like a thumb drive, will be available. At least this way we would be able to download files. However as off today, July 5th 2012, that is just a promise but the manufacturer's developing team has a good track record of implementing the most popular users requests.
  • Timex software for the Cycle Trainer does not recognize the GS-580P. It seems the Timex CycleTrainer and the GS-580P units have different firmware and require different drivers. Again as I noted earlier I wonder if the GS-580P can be flashed with the Timex Cycle trainer firmware, then the Timex software, available for Mac, would recognize it?
  • Some minor firmware annoyances Like selecting Imperial units (Miles/Ft) for distance/elevation and the temperature being displayed in Celsious instead of Fahrenheit.
  • Uploading data containing Hear Rate, Cadence, Power etc. to websites like Strava needs additional software, SportTracks and installing 2 plugins for it ("Globalsat Device Import" and "export2tcx")
  • Only 1 bike mount is included. it attaches to the stem or handlebars with zip ties which is fine if you never need to move the mount between two or more bikes but with a single bike mount in the package a more user friendly way of securing the mount would have been nice.

Other Notes: (To help me remember)
Adjust display contrast: Turn the device on by pressing Power/ESC and Down arrow/LAP buttons simultaneously.

Firmware upload failed and device won't respond? Press Power/ESC, OK and Up arrow simultaneously and for a few seconds. Then try again to upgrade the firmware.

Hola Victor,
Creo que todo depende del cubrimiento y la fuerza de la señal del satelite. Yo no he tenido problemas perdiendo la señal. En dias nublados puede ser mas dificil mantener una señal si estas debajo de muchos arboles o al fondo de un cañon entre dos montañas altas. Realmente cualquier GPS tendra el mismo problema. Yo creo que eso puede suceder en muy raras ocaciones.
No se a que te refieres con "es el zoom máximo al que puede trabajar" Este GPS se puede calibrar para que obtenga posicion cada segundo o a cualquier otro intervalo. Yo calibre el mio para que obtenga pocicion cada 3 segundos y las rutas aparecen perfectas en mi computador. Pero si subes rutas del computador a websites como los resultads varian por que cada website usa algoritmos diferentes para reducir el tamaño del archivo y al eliminar el numero de posiciones pues las rutas pierden fidelidad. Aqui hay un ejemplo de una de mis rutas despues de subirla a como veras tiene buena resolucion pero si hubiera subido la misma ruta a otro website el resultado probablemente hubiera sido diferente.

algunas dudas más.

Hola, compañero...
Espero no abusar de tu amabilidad...jeje. Tengo algunas dudas más, que paso a exponerte, a ver si puedes ayudarme.
1.- Veo que indicas que tu unidad ofrece la temperatura. Yo no he encontrado la forma de visualizar ese dato. ¿es posible que el mio no lo tenga?
2.- En mi anterior receptor GPS (Bryton Rider) se quedaba grabada la cantidad de kilómetros totales acumulados, de forma que en cualquier momento puedes ver cuantos km has hecho desde que empezaste a usar el receptor. ¿hay alguna forma de que el 580p haga lo mismo?
3.- Hay alguna forma de que la hora y el día se queden grabados? lo digo porque parece ser que cuando no tiene cobertura por satélites, no es capaz de actualizar la hora y la fecha. ¿te pasa a tí lo mismo?

de momento ya está todo. Cuando reciba el sensor de cadencia y de frecuencia cardiaca, me explicarás como subir los datos a strava. Veo que hay que hacer algo con sporttracker y también instalar un par de plugins.

un saludo y gracias por todo.

Hola Juan,

1)En el menu de Training Gym Pro (TGP):
Archivos de Ruta
Abrir para cargar en TGP la ruta que deseas navegar con el GPS

2)Una vez le ruta es abierta en TGP
Selecciona Transmision de Datos > Puntos de Ruta > Cargar al Dispositivo

3) en el GPS:

4)Selecciona la ruta que deseas de la lista. Ahi estan las rutas que el GPS had grabado y tu no has borrado del dispositivo y tambien las rutas que tu cargaste por medio de TGP en el paso 1.

Para Navegar seleccion SEG. ATRAS
Selecciona RARA EMP. (para navedar del final hacia al comienzo es decir en reveso)
Selecciona PARA FIN. (para navegar del comienzo hacia el final)

Dependiendo de la distancia de la ruta, este ultimo paso se demora desde solo usos segundos hasta 15-25 minutos o mas. Si la ruta que quieres navegar es una que gravaste en el pasado con el GPS el proceso es mucho mas rapido.

Reply #7 on : Thu February 27, 2014, 06:50:18
Hola de nuevo, compañero..

Ya he recibido el 580p, ayer mismo, y en principio va perfecto...salí a dar una vuelta con la bike y detectó en pocos minutos los satélites.
En casa, instalé el training gym que venía en un cd y actualicé el firmware a la versión 2.0.
Luego volqué el entrenamiento que acababa de hacer y pude observar la cantidad increible de parámetros para analizar. Todo genial...pero cuando intenté cargar una ruta en GPX en el 580p, fue imposible. Me decía "ruta cargada con éxito" pero cuando voy al menu "rutas" no hay nada dentro. También he intentado en formato KML, y me dice el training gym, "formato no reconocido" ¿qué estoy haciendo mal?
Muchisimas gracias por tu inestimable ayuda!!

Hola Juan, La respuesta corta Si. No he añadido esa parte a my review pero puedes subir (upload) al GPS rutas en formato KML y despues navegar la ruta hacia adelante o en reverso. La pantalla te da una linea que es muy facil de seguir. Yo he usado este GPS en rutas de montaña que no conosco. Ademas creo que tiene alarmas para indicar que estas alejado de la ruta pero yo no uso las alarmas. Yo voy a actualizar my review con una imagen de la funcion de trackback y una descripcion de como funciona.

hola, he visto que tienes este receptor de GPS y me pregunto si, además de grabar la ruta para volcarla al PC, también puede guiarte en rutas de montaña mediante algún tipo de indicador de sonido o de imagen.

Reply #4 on : Tue September 11, 2012, 12:41:08
No no le he puesto el firmware de Timex por que esta funcionando bien y no me molesta mucho tener que usar Windows para extraer la informacion. El Timex Cycle Trainer parece ser el mismo hardware pero el firmware es definitivamente diferente. Tal vez mas adelante me atreva a poner el firmware del Timex en el GlobalSat GS-580P pero no por ahora :)

Hola, estoy esperando que me llegue, lo compre en dx hace 10 días.
Al final te has "atrevido" a meterle el firmware de timex.. en la página de globalsat "afirman" que no se puede por que son productos diferentes (, pero yo no lo tengo tan claro...

re: Where did you buy your GB-580P?
Reply #2 on : Tue September 04, 2012, 22:38:19 As with everything I have ordered from it takes a while to get to the US (about 3-4 weeks but have not found a place that beats their prices. They also have decent customer service in case you have issues with your order. Good luck! I really like my GS-580P.

Where did you buy your GB-580P?
Reply #1 on : Tue September 04, 2012, 21:32:43
Could you let me know where you bought your Gps from? I'm considering getting it from but I want to be sure the dx one is authentic.
