My garmin streetpilot 2720 lost voicemail how to reinstall it back

You cannot unlock (or "reset") a locked unit without the PIN number or going to the location where the PIN was set. The only other option you have is to send the unit to Garmin.

There is no way to just "reset" the PIN. If you don't have the correct PIN, you must take the unit to the location at which the PIN was set. Your only other option is to return the unit to Garmin.

I didn't know I could access the Garmin File System... However the fix for me was simply moving the Demo Directory off the unit. (I put it on my PC just incase) The Unit works GREAT!!!!

I was told that you turn off the unit, hold down the FIND key and turn it on while holding. Keep pressed for about 10sec. then release.

SOURCE: touch screen won't calibrate on garmin 2720 gps

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
