In the early 2000s, I had to take my Garmin off the windshield and hide it in the trunk every time I parked, otherwise someone would break in and steal it. My car was broken into 3 times. Someone also stole my Microsoft Zune when I forgot to take that in with me.

Heck, this happened to me in the late 2010s...

Regarding point 2: When I worked for a valet parking company not too many years ago it would astonish me how many people would 'remember' they must secure their GPS in the glove box, despite leaving much more expensive items like iphones/laptops/purses/wallets in plain sight strown around within their vehicle. They were an easy and common theft target at one time I guess .

In 2009 somebody smashed my car's window to steal my garmin. Even if the GPS is worth little, they are worth hiding because thieves are morons who will smash your window for it anyway.

Anything in a car is a theft target. I've had a window smashed so someone could steal my $7 knockoff lightning cable.

In the UK, we were reminded to clean the inside of the windscreen to remove the telltale suction cup marks, so thieves wouldn't assume there was likely a satnav hidden in the glovebox or boot. (Windscreen = Windshield, Boot = Trunk)

Can confirm. Had a Garmin/Palm handheld (iQue 3200 or sth) with Garmin mapping software for Windows to prepare/preload map tiles onto SD cards, plus a complex setup involving VirtualPC and NoMachine NX to make it run on my PowerBook.

A lot of people have entirely different perceptions of risk than actual risk exposure.
