I recently bought a 2012 SRX and my Iphone 7 will bluetooth to the system for phone but nothing else. Having to use an aux cable to be able to stream music but has to be controlled with the phone. GM has confirmed based on the VIN this is operating as expected. I'd like to replace the system with something more modern but the two places I've taken it indicate 'those cars are not made to be modified'. I would appreciate suggestions. The aux is working but I prefer the hands free. Thank you.
