I have an 06 with the carver system as well and unless you are looking to dump over a grand into it, the aux is the best bet. Personally, I just do an FM transmitter which works pretty well for my needs. I dont even have an aux installed. https://www.amazon.com/AUKEY-Transmitter-Bluetooth-Wireless-Handsfree/dp/B07F5H84HT/ref=sr_1_3?dchild=1&keywords=aukey+fm+transmitter&qid=1586792089&sr=8-3
