I'm done with this 430nRHB issue
. It will skip and play fast with an iphone4 on Bluetooth streaming unless u press the phone lock button. It will have poor visibility, low brightness, low contrast in daylight (FAR INFERIOR TO THE 730n or ANY other backup camera I've ever seen) that is not controllable. I just drove to my dealer and checked the tsb 08-019-12 and i'm up to date. TA DA DONE! And thanks for all the input.
