I had my CD unit replaced on my 54 plate free of charge, took it back to the dealer without any hassle. The only problem was bose were along time sending another unit, nearly 6 weeks. Because bose kept saying the part was on its way the dealer thought it wasn't worth putting the car back together again and messed about for nearly 6 weeks and I had the shame of driving around in a Note , I did save loads of money on fuel, I also got laughed at by my so called friends.
