After catching a ride in my mothers van (a Toyota Sienna) - I noticed that it has a auto dimming mirror WITH a compass and outside temp guage. Since we were already making a trip to the Nissan I asked about a similar product for the X's. They do have them (listed as an optional extra for the 2k1's). I wanted to know if anyone has tried to install one of these yet on their X. The two questions I have are 1- where did you wire it into the electrical system (since something has to power it) and 2- where does the temp guage go?
