I have a Garmin nuvi 650 car gps (2 years old) and the screen has started to freeze up. I followed the manual instructions and pressed to get the pre-boot mode. It worked for a short period of time. Then the other day I used it for a trip and on my way the screen froze again. I tried to hit the pre-boot mode but it didn't work. What is the problem?

Try these two reset procedures

Procedure 1:
1)disconnect nuvi from external power
2)Flip up GPS antenna
3)Press the reset button
4)Connect nuvi to power source. The nuvi should turn back on and operate normally


procedure 2:
1)Hold your finger on the upper-right corner of the nuvi's screen while you turn it on. keep your finger until the pop-up window appears
2)Touch YES. All factory settings are restored. Your recent selections and audio bookmarks are also deleted

Waking up your c330...

If you left your Garmin c330 on running the battery will have 1% life left. If you turn c330 back on again, it will flash screen for 3 seconds then die, even charging it at this point will not wake it back up. TO BRING IT BACK TO LIFE... plug in the power home or car into Garmin c330. There is a tab in the front Garmin gray frame of your screen. You must take like your fingernails and under the logo "GARMIN" pull the whole gray plastic frame off. Underneath the plastic frame to the right hand side. There is a "RESET" button. Make sure power is plugged in while hitting reset. Your battery should come back to life. Cheers
