DO NOT BUY ANYTHING FROM THIS SELLER. I purchased the headunit, the seller claims it was working fine before he shipped it. After installing it 90% of the discs I tested did not work and gave the error code E20. The unit was packaged improperly and was most likely damaged during shipping. The seller did not offer insurance and shipped the item uninsured, he also blames the malfunction on me and refuses to refund my money!
