Are there any hidden features on the eTrex?
A. Yes. Try holding down the PAGE and PAGE UP buttons while you power the unit up. The unit will enter the service mode and display: Bravo Version Software Version Time Internal temperature of unit Battery voltage External voltage Button presses Other tech info You can do a LCD screen check by pressing the PAGE button twice Caution: While entering the service mode is interesting and useful, be careful which buttons you press because it is also possible to rest the unit to factory settings within this mode. Pressing “up”+”enter”+”on/off” keys in service mode will reset the eTrex to factory defaults. All presets and data will be lost. To exit just turn it off as normal, and then turn it back on as normal. Unless you deliberately reset the GPS, nothing should have changed. – Ben J A. This is about invoking the service mode in eTrex. I recently bought an eTrex Vista, and upgraded its firmware from 2.12 to 2.16. I tried to invoke the service mode as mentioned in the FAQ, but it didn’t work.
