Question about Garmin nuvi 350 GPS Receiver
I have had the Nuvi for 2 years. The touch screen does not work all of a sudden. Tried resetting the device, but I cannot get beyond the password ( cannot enter as the touch screen is not working ). Tried holding the power button to reset. It ran through pre-boot, then software load, but it just ended up coming to the password screen.
The touch screen lays on top of the LCD display. It has its own flex cable that plugs into the main board. It is possible for the LCD display to work fine while the touch screen does not. They are two separate parts and work independently!
If your touch screen all of a sudden quit working, I would ask did you ever drop it?
I have repaired many Nuvi's with a non-functioning touch screen. I can't speak for every instance but the ones i took apart, the flex screen cable was loose from the main board.
Don't attempt to fix this yourself unless you know what your doing. Email me at ks3r at sharc dot net if your interested in me repairing your Nuvi at a reasonable price. I have references.
