Summary: I bought it with garmin street pilot 2620 because the windshield on my car was tinted, coated, and heat treated. With this product, I never lost any signal reception and installation and uninstallation was so easy to handle anybody. Highly recommended.

Summary: Installation of the Garmin GA 27c Low profile remote automobile antenna did increase signal strength and I have not lost satellite reception on my Garmin i5 receiver. The cable could be a little longerfor extenal installation.

Summary: i had garmin 3600, had a problem with it especially deriving, if you take acute turns, there is tendency for PDA to tilt or fall away on the floor, even i used garmin cradle and bean bag. Having it would solve my problem! i found it very useful.
