• Wich Garmin models fail you so often? :( I've the Edge 810 for about a year and it turned off itself twice before hitting 40 ºC (104 ºF). The Bryton and TwoNav seem like great alternatives but still hasn't read about anyone audaxing with them (Carlos Mazon is using a brand new TwoNav Anima+, but still for training rides)

  • 800 and 810 both fail. 800 is more reliable but can die after 400k, though seemingly only when navigating because it always worked during 24hrs. 810 froze all the time, was repaired but then randomly turned off and lost data. Waiting for refund. Might try Edge 1000 but not sure it's worth it.

  • Reading up the eTrex 35 Touch, my dad gonna get one for walking and cycling, will let you know about the cycling aspect of it.

  • That really worries me :( I've never ridden more than 200k with it, and now I fear my 810 will behave that bad too...

    I've asked my local long distance community for their experience, some used the 810 on the 2013 MGM (http://www.strava.com/activities/76987571) and got problems on the final km... their advice is to break the route file you're following into 3 or 4 files, and also start with the device clean of training records. Maybe you tried to follow a big route file the times you got the freezing problems?

    The fastest rider of the PBP apparently had no problems with the Edge 1000: https://www.strava.com/activities/372806960

    I can't find any info or experiences using a Bryton or TwoNav for long distances...

    Maybe the solution is to downgrade to a unit without maps and the TBT functionality that seems to be the main problem (Edge 500 / 520) and just load a route with handmade waypoints for each complicated turn (that will also serve to study the course). I've used an Edge 305 for almost 7 years without an issue (apart from battery degradation), but sometimes a tight 'Y' type intersection was hard to take without error while going fast or offroad
