So finally! I finally got car play to work and media hub is working (although not sure what I did tbh). I also bought the Magic Brand Magic Box so my car play is also wireless! So im super stoked! But, I tried connecting my thumb drive with the connect update and its saying that it won't read it. Do I need a certain thumb drive?
I agree with setkneelbend if everything is working let it be.curious what your current application is.since you replaced the motherboard it is probably different than what you had .if you wouldn't mind pm me the ebay sellers name.i have all the parts for another unit I am just missing the motherboard.
I have the same problem with my old RA4, it will music from the USB, I bought the Uconnect MAP update but when it is inserted it say it can read the drive. So I called HERE tchsupport and they said it was the radio so I just quit trying.
