Seat no problem yet, beside leather cracking marks. Just ordered the leather pristine rejuvenator to help the seats. They are so soft I am afraid that may have problems in the future. Where exactly do you feel the pinch? Or do you see seat leather not aligning? You have mentioned side of the seat. Can you take a picture and I look if this is common thing. I may not have noticed yet.
DVD screens are useless to me. Took me a while to make them play from the phone through a pairing cable. The codec is weird and don't play anything from thumb drive, etc.... Mirroring the phone made it work. I need to try pivoting them and see if I am having any problems like yours.
Satellite radio has no problems until I get to parking garages, etc which is expected. Quality of sounds is bad anyway due to compression, so as soon as free subscriptions runs out I will come back to local station which sound much better and personal MP3s.
