I figure a pro installer would know whether or not the already existing USB/3.5 analogue inputs found inside the glove box on my parents car(2012 Buick Enclave), BEFORE they had the dealer outsource the vehicle to a car audio shop, in order to replace the non-nav unit with a factory OEM navigation HU, could simply be plugged into the back of the new nav HU.
They now have a factory supplied OEM NAV unit installed that wasn't originally installed into the SUV when it was built. I tried using the 3.5mm analogue input with my Mp3 player(not an Apple), to no avail.
This leaves me wondering whether or not the aftermarket installer could have failed to connect the USB/3.5 input cable to the rear of the new nav HU.
Or perhaps(this is why I thought a pro installer would probably know the answer) the audio inputs are automatically included inside the glove box at the factory, but that this particular VIN wasn't built with a high enough options package to include an audio HU with a rear jack to accept a connection from the AUX audio input cable(s)?
All I know is I want it working, since I borrow it occasionally to go on long trips. I don't want to risk scratching any trim trying to get it out to see if there is a rear, AUX input or not.
I thought, perhaps someone who is a current installer might know the answer.
