I am looking for VW NAVI units. I am about to recieve the FIS Cluster any day, Part # 1J5 920 946 C, in MPH and coded for Miles to empty. I have the sterring wheel controls and the Monsoon. My question is what version of NAVI to get? I understand both version D and G will both interface with the FIS cluster, but there is a question weather or not version D will interface with the steering wheel controls.. Any ideas? I have been to www.vwnavi.com, and the consensus is that no one is really for sure.
