I would agree on the bad ground connection. I have the Shaker 500 and installed the Kenwood DNX570HD (2013 model) w/ Maestro RR and have no issues. Sound is better than OEM and so far I love it.
I'm currently using the Metra touch screen dash kit and it's really growing on me, but I would consider switching to the iDatalink dash kit if they ever release the dam thing. Last I heard they were gonna ship in August but it's the end of August and still no update...sigh
Anyway since this post is 4 months old I'm sure you've got this sorted by now but for anyone searching this issue, double check your ground connection!
I too have the DNX570HD and the Metra w/Maestro RR. Quite pleased with the system. The only problem I have is the Garmin map updates are not available for this unit, can't even purchase lifetime updates from Garmin. When and if updates are available, Kenwood wants 99.00 for each update. I am really pissed about this. I bought the unit partly on the strength of the Garmin GPS. IMHO bad customer support. If Kenwood is going to offer Garmin, then do it right. Wish I had gone with a Pioneer now!
