Ordered this several months ago and it came within a couple of days, but only got around to installing it last weekend. Installation is just 3 wires (ground, permanently on +12V and an ignition switched +12V. I found all the necessary voltages easily in my 1973 Porsche and installation literally took 15 minutes. Didn't even need a voltmeter if you use logic. Ground is easy, +12V came from the clock and +12V switch came from the wiper motor connections. Even in my garage the GPS worked perfectly and had positioning information within 15 minutes of me setting up an account. It's very slim and easy to hide. I won't say where of course. The app is simple but works fine and has useful information. I'm really only interested in location and it seems to be accurate to within 10-20 feet. Enough to track my car if ever stolen. My car is insured with Hagerty and at least in Ontario, they give you a discount if you have a tracker. Of course, that discount is about what the annual fee of the tracker is, so you don't actually save money, but I do get some peace of mind. Highly recommended.
