Question about GPS Devices
So what happens when you connect it to the PC?
Make sure no sd cards are installed while you do this.
download and install web updater, run it it gets to a screen where it looks for the gps, plug the usb cable into the GPS (no USB hubs please!!!) Make sure it detects the GPS before you continue. Select the updates you need (don't install all the languages !!) after this is done the program will report the downloads are on the garmin, unplug the unit and it will reboot and whilst rebooting it will install the updates....so don't touch it until it reboots again and displays the regular screen....and make sure the batery is fully charged before you do this...!

The touch screen is a 4 wire resistive type made up of several layers. A thin plastic layer, a micro thin metal layer, microdots for insulators, another ultra thin metal layer, and a final plastic layer. All of these layers amount to the thickness of a sheet of paper. This whole stack is bonded to a thin sheet of glass and placed over the actual TFT display.
It's amazing that you can see through all these layers and only lose 20% of the light. What's not so amazing is that those thin metal layers are prone to damage. I've seen several with no apparent damage that didn't work, and several with visible scratches or cuts that worked fine.
I usually start by installing (or reinstalling) v7.2 firmware and then attempt to recalibrate the screen, sometimes that works. Next I would try re-seating the 4 conductor touch screen pigtail in it's ZIF socket nestled between the big white wires on the display assembly. The last resort is to buy a broken 2600 or 2700 series Garmin and salvage the touch screen. You could send it to Garmin for a flat $250, but that makes no sense at all.
If you get another screen (Garmin won't sell you one), Here's how to replace it:
Remove the six screw holding the case together.
Split the cases and pull the patch antenna out of it's slot.
Remove the four silver screws holding the display assembly into the front bezel.
Unhook the small ribbon cable that goes to the infrared receiver under the red lens.
Pull the display assembly out of the front bezel. It won't come all the way out because of cables.
Use a razor to cut the plastic tape holding the touch screen bracket to the TFT display.
Unlatch the 4 conductor ribbon from the ZIF connector nestled between the 2 big white wires.
Use a penknife to unbend the metal tabs keeping the touch screen from coming loose. I usually just do the two by the IR receiver.
When you reassemble, don't get frustrated with the gaskets, they're tricky but it can be done. Tom

Sounds like you need to recalibrate the screen. This can be done by following the steps below:
To Calibrate the Touch Screen on a zūmo®:
1. Turn the unit Off and make sure it is not attached to any outside power source.
2. Power the unit On, continue to hold the Power button for 1 minute. 3. A screen will display that says, Press dot in the lower left corner. 4. Release the Power button and touch the sequence of dots until your unit says Calibration complete.
