PNI Wayfinder Temperature and Compass System
A Fun Compass/Thermometer
In other reviews, you will see some downsides to this compass, like a weak backlight and small readout for temperature.  It may depend upon your age.  The temperature is just a little too far away for bifocals.  But it's readable.  The light is too weak.  Installing the remote sensor was a snap, but it may depend upon the configuration of your auto grill.  I took my license plate off and attached it to the grill behind.  Simple.  The people who had to go out to buy a Philips screwdriver probably should have one anyway.  The best part about this electronic compass, besides the ease of setup (press a button and drive the car in a complete circle) is that there is an indicator that travels around the compase rose so you can tell exactly what direction you are headed.  The large N, NW, W, etc., readout is the same as with many of these electronic compasses--it will stick on one direction until it gets close to the next, and then changes, so it isn't quite as accurate as a floating compass.  But that constantly moving indicator that travels around the readout overcomes this if you want to be persnickety about the exact direction.
