I have a 2008 VRX Olympic edition with MMCS Ver A01 Rockford Fosgate, I went to the local dealer and the Mits spare parts system reported no iPod cable was supported. I pulled the dash apart in the dealer driveway and the spare parts guy helped me out by opening a current version iPod cable to test.
Plugged it in and it work perfectly with an iPhone 4s.
The cable part number is MR936970. See photos (hope the link works)
Cheers,

Cable and docs
 
Back of unit with iPod and reversing camera ports
 
391 tracks on my iPhone 4s. The iPod shows up where the Aux normally does when you select "Mode" in Audio
 
Part number on the bag from Mits Australia - all good
This cable does not charge the iPhone 4s, it needs to be moded or you can buy an adaptor from Mits for $40. I will cut the cable open and add the resistor network later (info on iPhone charging circuits is on the Web)













 and I live in Victoria. I am having issues with the 1st gen MMCS, for one I can not set the time on it, I know it is connected to the satellite GPS and to set the time you have to set the time zone and if its daylight savings time or not, but it wont allow me to do either of those. All the options on the set clock screen are greyed out except for choosing 24hr or 12hr format. When I look at the connection details screen, where it says satellite there is just a 0, basically meaning there is no signal. Is this normal in Victoria or is there something wrong or am I missing some key component ?
