I see it has been a few days and I just wanted to follow up to see if you have any more questions concerning this issue or if the issue was resolved.
I didn't see a response back to my questions, but wanted to send the following information.
There are usually two ways to have the screen replaced, which is by Garmin - via their repair service - and by a third party. So I have links to those two places, where you can check to see if your particular model can be repaired, and the cost. Then I would compare that cost to a new device, and see if it is better to repair or replace.
Click Here --> Garmin Repair Page
Once on the page, select your Model from the pull-down list, to get the price quote, and then scroll down to see the rest of the process.
Click Here --> Third Party Repairs
On this page, look for the "Request Quote" button on the left of the page, and submit your information to get a quote.
NOTE: These folks get very busy at times, so if you see "Schedule Full" on the quote page, come back a couple of times each day and REFRESH your browser screen - to get the request page to appear.
If you want to check the prices of newer units, I have a link to a search I did on Amazon, showing the current "Nuvi LM" devices (come with "Lifetime Map" updates).

I look forward to any further questions or results that you may have.
Thanks, ***** *****
