Temp and Compasses on rearview Mirrors and Overhead consoles

Does anyone know whether the temperature and compasses on rearview mirrors and overhead consoles need other parts to make them functional or are all the parts contained in the unit.

That is, if I were to put an overhead console or rearview mirror from a newer car into my older car would the compass and/or temperature be functional by just wiring up the unit or would I need some sort of sensors?

I can only tell you about late model G.M. The do have a temp sensor in the grill that is very similar to the intake air temperature sensor in the snorkel
between the throttle body and the air box. Some of them the compass calibration is controlled via class 2 communication circuit in the body control module. Look into the aftermarket ones, I've seen them advertised and they should be self contained and easier to install into something that didn't originally have one.

good luck.

Temp & Compass

Doc here,

If you want an OAT (outside Air Temp) gauge, you need an external sender...

If you get a "Whiskey" (wet) compass, It is stand alone..

You can find both at an airport instrument shop..but their expensive..(anything with a TSO is..) And then you'd have to fabricate a mount for both too...

Cheapie Instruments are available , as was said, aftermarket at the auto parts supermarket ... (next to the fragrance trees.. )
