Question about Garmin nuvi 750 GPS Receiver
Just reset the GPS and check whether it helps you or not. To reset do the following.
Slide the power key to the left and hold it there for a minimum of 10 seconds. The nuvi should operate normally.
If this does not help update the software. Goto www.gramin.com/products/webupdater

SOURCE: trouble with Garmin 750
Even stand alone FM transmitters are tempermental and their performance
can depend on the arrangement of your car's antenna system.
I have found that my radio will 'lock and hold' the Garmin's signal if I can boost it for a few seconds by creating a stronger signal by placing an 'antenna' (generally anything metal) near back case of the Garmin at the middle or right side (looking from the front).
You can also try just taping a piece of metal to case back at that position. I just used pair of sissors but I'm sure some tin foil or a peice of wire will do the trick.

Move the on/off power switch to the left and hold it there for at least 30 seconds and see if it comes back on. I know there was a bug in a firmware version that makes the unit "bricked" after a certain date. The only way to fix it if the reset didn't fix it is to disconnect the battery inside, reboot the unit and install the firmware fix.
