I use the aux jack and it's always plug into my twin dvd's on my headrest. Sound is awesome compared to the crappy radio sound I get. Considering it's the base model you can get theater surround sound in Rogue. Umm not really...lol, but 4 speakers.
I understand why you might be damaging the aux jack since the plug sticks out.
Do what I did and go to Radio Shack and get the right angle adaptor. It is not obtrusive when the cable is plugged that way and I never had any problems of it breaking. Somebody may be accidently pulling at your plug too hard perhaps.
Also here is a comment from a radio shack user:
Comments about RadioShack 1/8" Right-Angle Adapter:
This is a great product. I was looking for a compact right-angle adapter that didn't have a cord between the ends. A random perk is that when it's plugged into the side of my laptop if I move too much
the adapter acts as a break-away instead of breaking the headphones or laptop port.
