    Hi!

    My car has a built-in GPS antenna and it is connected to my car's navigation.
    My car also has a special coating, that absorbs UV light, but it also absorbs many EM signals (like GPS).
    The problem is that the built in navigation is useless (no maps) and lacks a lot of features, so I prefer Waze on my phone, but there is no GPS signal in my car.

    The only way I can think of (without changing my car's windows) how to make Waze working is to connect the car's GPS antenna to a Bluetooth module and pair the phone with it.

    My question is... Is it possible?
    Currently I'm just looking if there is something that would prevent this system from working.
    The principle should be simple:
    I get a working bluetooth GPS module, solder the car's GPS antenna to the bluetooth module, solder a voltage regulator (in case the module works in 5VDC) and solder a 12V cable from the car.

    Everything seems fine, but could there be a problem with the "external antenna"?
    I know that Wi-Fi antennas needs a specific inductance so you can't just "make the antenna longer with a cable". Are there similar problems with GPS antennas?
