Sorry if this has been covered before, but if so I can't find the right thread. I have a 2007 RL Canadian model OEM radio,6 disc changer, aux button but no XM button, no Nav, but with subwoofer. I've ordered a USASpec BT45-HON3 Bluetooth adapter, that has an extra aux input port. Ideally, I'd like a tuner that can plug into the aux input of the BT adapter so that all the wiring will be behind the dash and not visible. Am having trouble identifying a tuner that doesn't require an "XM Ready" input. Any suggestions would be much appreciated!
