    My trusty 2720 started acting up on Sunday and even after a master reset the problem was still there. Turn on and go though boot-up and it prompts for screen calibration. That's obviously not normal. Pressing the screen as instructed gives a cross hair but it continues to ask for screen presses, seems stuck in a loop.

    As the unit is no longer supported by Garmin I decided I had nothing to lose by taking it apart to see if I could fix it myself.

    I set the GPS on a tea towel to stop it skidding about on the table and damaging itself.

    There are 7 screws in the back of the unit.

    [​IMG]

    With all the screws removed hinge the adjustable bracket back out of the way

    Gently split the unit open and this is what you see inside

    Carefully lift the antennae and little silver plate up and back out of the way

    There are three little screws holding the green circuit board in place and a further four around the edge of the electronics. With hindsight I didn't actually need to remove the circuit board, I could have just loosened the four screws around the side and lifted the innards all out.

    Be very careful not to damage the little wires and ribbons which link the various elements

    And clean the screen, rubber seal and the inside of the outer shell of the GPS. There was some dust and dirt around the seal and the screen some of it quite gritty.

    [​IMG]

    Set the innards back into the shell and be gentle with the antenna.

    [​IMG]

    All back together again and ready to be closed up. Tighten the srews in the shell as tightly as you can without damaging them

    My 2720 is now back working again so the spare 2610 I have can go back into it's box again. :)

    It's a very simple job to do yourself and may well save you the price of a costly repair.

    thanks!

    Do you know if the touch screen can be easily replaced by a commodity part?
    If so, any ideas where the part can be purchased?

    Hi, I have two bmw navigator II's. One with v9 maps on and the other with v7 on it. The V7 one is in better condition - outer casing and screen), so I was thinking of taking the v9 internals out and inserting it into the less worn out V7 item.
    Thanks for this, as mentioned in a previous post, it gives re-assurance to those who have 'something to loose'.

    Note: I cannot upgrade the v7 to v9 maps as I don't have the unlock codes and garmin don't give them out any more :-(

    I've seen digitizing screens for Streetpilots on ebay.

    I'm in the same boat. That sucks too. Working on that right now.

    Mine just started doing the same thing. Going to try your fix.

    I just replaced the digitizer screen that delaminated on my Streetpilot. Bought the replacement screen on ebay and it was a pretty straightforward job with using your pictures as a guide.

    I know the OP was a few years ago, but I was having the same trouble and this fix really does solve the issue. I always like to bump the helpful posts incase someone comes across this problem again in the future.

    Also, those of you who still use the Street Pilots, I would go ahead and do this now before you get stuck many miles from homes when this starts to happen. I was in Arkansas when mine went down and I live in Central Indiana.

    Ill ad that it is important to remove ALL of the old adhesive. The first time I did this job I must have left a bit and it caused my new digitizer to crack when I tightened the shell back together. A little Goo B Gone on a cloth does the job.
