PNI Wayfinder Temperature and Compass System
Still Lost in the Dark
This compass wasn't easy to set up.  First,  I had to buy a tiny Phillips screwdrive to open the case in order to insert the battery for the temperature transmitter.  My husband, who is in construction, didn't have the correct screw driver in one of his many tool boxes.  In order to attach the thermometer transmitter, I had to lie down in a driveway and search for a place to attach the device under the front of the car (if I were younger, this might have been easier).  After getting this accomplished, I discovered that the backlight display on the compass (which has an easy to open battery compartment & an optional cigarette lighter power source) doesn't really work in the dark.  During the day it is a reassuring device.  I have yet to find out whether the icy roads warning device will function during the upcoming winter months. A rather pricey gadget.
