GPS has really come down in price. You can get one in a store for $50 now so IMO I don't think it's that much of a draw. In my 4Runner the GPS is always on the dash and I haven't had a problem. I've parked in Philly/NY/DC and no one has messed with it. YMMV though.

 

I'm using an Aukey magnetic mount in my GTI & my wife's MINI. Clips into the vent & works well. Bought a couple from Amazon.

 

@2Rismo2: I agree in some ways. Most of the advice online is a few years old, and the way that smartphone functionality has made inroads into GPS navigation has really changed the situation. At roughly $50 per dedicated GPS device, however, I'm still a bit hesitant to assume that thieves won't be attracted. These guys are not sophisticated big-time thieves going after lucrative steals. They're probably on the fringes, maybe even looking to score enough to get their next fix. I don't want to pay dearly in terms of time to fix something at many times the cost of what the burglar was seeking (whether they find it or not). The fact that you haven't had problems is valuable information about the trend, given how rapidly things have changed. Thank you.

@ashchuckton: Thanks, a friend of a sibly also suggested Aukey. I'm shying away from magnetic binding right now because of my technology background. It's probably nothing, but there is no need to take the risk, so why bother. I'm also avoiding vent anchoring because I use the heat in the winter time, and don't want the phone to get blasted by it (especially with the battery and all).
