Still running my 2820 and 2720 and I just updated the maps on both. I got in on the lifetime map updates. I figure its paid for itself by now.BecketMa said:Great find John!
if they didn't charge so much for an updated map I'd be running one of my older units.

I have had it apart at least four times and have tried heating the screen with a heat gun, cleaning it, etc. Put it back together and it works fine until it touches itself!johnbaker15 said:John,
Not sure what you were saying about a screen bing touched, unless you were saying it got touched to hard.
I have read on the internet (since its on the internet it has to be true ) that dust can get between the screen and the gasket/seal and this will throw off the calibration. The solution was to remove the front cover, clean the screen and the rubber gasket on the cover.
