Need help to revive a nüvi 765 (if possible at all...)
Got a dead nüvi 765 from a friend. Symptoms are as follows:
- When sliding on/off switch to 'ON' position, unit does not power up (no screen activity, no sound).
- When attaching to home charger, unit does not power up (no screen activity, no sound).
- When attaching to PC via USB cable, unit does not enter mass storage mode (no screen activity, no sound, no PC response).
- After replacing battery by new one (and fully charged in another unit!), same symptoms.
- Unable to enter pre-boot mode.
Anything I could still try to get this unit back to live?

It's dead almost certainly by what you've tried. Last gasp attempts: Hold power slide to left, connect to rear port of PC and hold to left for as long as possible [at least several minutes]. If it doesn't wake up, open it again and disconnect the battery for an hour or so preferably overnight. If neither works strip it for parts because someone's played with it a bit too much and killed it probably. I've got a 265W and 255W from ebay like that, dead as dodos nothing worked to wake them. Happens eventually to us all who buy 'bricked' units cheap. The mongrel who sold me the 255W had even substituted a non-working screen and dead battery so only the case was immediately salvageable after i went to the trouble to swap both screen and battery to another working unit to test.

Held it for just over 4 minutes, then my (numb) finger slipped off the button. No life noticed. Originally Posted by Neil
