For a start it all depends on what system you have to start with, so we can't answer that until you provide your VIN. Please post your VIN in full without spaces - it will be automatically masked from public view after submitting your post & will only be visible to staff.

Once I have this I may be able to help. But be aware an AUX port isn't much use - it was only intended for old music players and provides no track, RWD or FWD control - only volume. Older systems are extremely limited. So you can only for Bluetooth use a third party device that communicates over a spare radio frequency to the Head Unit.
