Hello, my Garmin 670 froze up on me and the touch pad does not work. I reset the unit several times without luck!! Can you help? Thank You Frank

I also have a Garmin 670 that would freeze on me every once in a while. The very first time I tried to calibrate it to no avail. It seems that if I don't use it for a few days the problem would recur. I suspected that the memory that stores some critical data does not hold because of the low battery. I then used the charger (the one that uses the electric outlet in the house) to charge it. Three days lalater, I realized that the charger was still charging the unit. Without much expection, I turned on the unit and it worked surprisingly. Since then everytime the screen freezes, I would charge it in the house for a couple of days, and it would work again.

You might just need to recalibrate the screen. Start by getting to the SETTINGS > DISPLAY page. Select RECALIBRATE and follow the directions.

Now, if the screen doesn't respond at all, you'll probably have to arrange for service. Contact Garmin Support for additional help with your nuvi 670 below:

I hope this helps!
