My experience with Garmin, as most of you have heared before, was “Its great if the route is pre-planned and loaded as a Route.”
My problem was that in Birmingham’s sprawl, I couldn’t get settings that let it work as a ‘SatNav’ in a ‘point and shoot’ cycle courier manner.
For Audax, the eTrex 30 is up in the top echelon of Nav devices, IF the route is sorted and loaded before the event.
Its also good at ‘Point and shoot’ when the user is in a rural environment well away from Mways and dual carriageways.
I bought a GPSMAP 62 with OS pre-loaded in the sale last year but took it back. For nav in the city, it still wasn’t as effective as the TomTom UR.
If Audax was all I did on a bike, I’d have an eTrex 30 tomorrow.
