I've been searching here and other various forums the past few days trying to find a solid answer. I just bought a used 2012 scab and it's all great except the stock nav unit. It's terrible. I'm really wanting to run the Kenwood DNX875s instead. I've seen some who have said it can be done and others who says it can't. I've talked to a tech a crutchfield and he said it can't. I've read about the iDatalink Maestro and their website leads me to believe that it should work but it's also not extremely clear. Does anyone know definitively if it can be without losing features or what features are lost by doing it? Any help would be great, thanks.
