Large dampness inside my screen on my garmin nuvi 1450. how do i clean it, is this a sealed unit
The Gamins are not sealed. You might try putting in a zip lock bag full of uncooked rice and leaving it for a few days. The rice will absorb the moisture that is in your GPS.

Hello Bonnie, http://beta.fixya.com/users/mc1bean
Hello Thomas,
Maybe this will help you some. I have found you the complete manual
which covers most of the models of the Garmin Nuvi. It is the full
manual from start to finish with complete operating procedures as well
as schematics, operation instructions complete with pictures, and
trouble shooting section and even other contact numbers to deal direct
with Garmin, if your model is not covered in this manual.
Here is the link for you:

Also if you can, please rate my solution if you can and some kind words
would be appreciated. I also took the liberty to put my link at the
bottom of this page that directs you to my personal page for all my
areas of expertize, such as Automotive, Appliance, Electronics. Feel
free to check it out anytime and save my link for future problem. Thanks
So, Much Mike.
