I know very little about this, but would love to buy a portable navigation system. My only concern is that it's very easy to put in (suction to the windshield or dashboard), but just as easy to steal. I would think that putting a 500-600 dollar devices in a car that's so easy to remove is an invitation for the potential thief to break into the car and take it.
Is there a solution to this problem? Is there a way to install the portable GPS unit securely in the car? I would hate to take it off any time I leave my car parked for several hours in the city.
Thanks!
