Garmin 760 sound

My garmin nuvi 760 has lost all sound. None of the mutes are checked and it
is not set up for FM. Any suggestions?

Maybe try if sound still works with a headphone. That could help
locate the defect (speaker or electronics) and maybe even help fix the
problem: plugging in a headphone usually switches off the speaker,
maybe yours got stuck?

My 760 has been soundless since last year. Some of the Nuvi's,
including the 760, apparently have a tendency for the headphone jack
to lift off the printed circuit board, with ensuing havoc. I've
checked a couple of repair shops/sites and they say it's a common
problem. The fix for this problem is to carefully reattach the jack to
the board, which is generally not a user serviceable task, or replace
the unit (refurbished through Garmin for $99, for example). I simply
chose to live with it for now.

Not sure if you have the exact same problem, but it seems like it. On
mine, if I *partially* insert a headphone plug I can kinda sorta get
audio from one of the two stereo channels, but only while I hold the
plug just right.
