I have a nuvi 205 that gives me touchscreen problems once a week or 2.

The problem is every week or so the touchscreen looses its calibration and the touch is always off. I press a icon and the other side of the screen presses. After I reset it and re calibrate it then it may work for a week and then it does it again.

I calibrated and then deleted the GUPDATE.GCD file and then re-calibrated again and updated the firmware but it did not solve the issue.

I was wondering if anyone could make sense out of this? I do not think the touchscreen digitizer is damaged because it will work for a week with no issues and then do this again.

This has been a problem for the past year.
