Question about Garmin (010-00583-00) for nuvi 750/760/770
Version 4.60 software.
No sound (turn ahead, etc.), but the stored preloaded media player files sound fine.
Under tools/settings/language check to make sure you have a voice with "TTS" after it, it means Text To Speech. Make sure one of those are selected and see if it helps.

Let me first start by saying that for the $$ I paid for this thing I
think it is really screwed up that so many people are having the exact
same problem and I truly hope Garmin fixes the glitch. Now - on to the
fix..... Before getting started, you should test my theory to see if
the reason you no longer have sound was the same reason as I had. Turn
the unit on and ensure all the setting indicate that FM transmitter is
OFF and volume is not muted. Go to the volume adjustment screen and
while adjusting the volume up and down you should apply pressure to the
back left side of the unit with your fingers. I found the sweet spot to
be about 1/4 distance down from the top and 1/4 distance from the left
of the unit. Now, while pushing in at this location on the back of the
unit with your left hand pointer and middle fingers, click the volume
buttons up and down with your thumbs and if you hear sound... then it's
time for the SIMPLE repair!!!
There are 2 small torx screws located on the back of the device down at the bottom. I didn't have a torx bit this small but I did have an allen key that worked. take out the 2 screws and open the back plate, don't be scared. Once open you will see 2 sets of wires connecting the back plate to the main board, one is the power cable coming from the battery which is affixed to the inside of the back cover, and also the speaker wire. I had plenty of room to perform my fix without any need to disconnect these wires, just be sure to pop it open gently as to not damage the wires but trust me - you will have plenty of room to work with. On the mainboard side of the device you will see a square chip-looking thing mounted onto a metal plate which protects the mainboard. All I did was put a glob of hot glue onto this chip. The glob should sit about 1/4 of an inch high. Let the glue dry. Place the back cover back in place and screw it back together. Done. If you don't have a hot glue gun then by all means feel free to use anything that is roughly 1/4 inch in width such as a folded up piece of paper or perhaps or whatever else you want to use. If your's was like mine then you are set to go and this problem should not rear it's VERY ugly head again.
