I have done my research, but there might have been a thread I missed. I have a 2006 passat value edition without steering wheel controls. I have a Mechanical Engineering degree, and I know my way around cars. I've installed countless radio's and audio systems without any problems, except this one. I purchased one the $400 dvd/navi systems off ebay.
All went well...I purchases a sosche wire harness along with the adapter for the antenna. My battery keeps draining after a day. I read about the VW's having 2 +12v wires, and my radio does need to be powered off and on manually. I'm okay with that...the battery draining is the problem.
I've read about the C2R-VW2, but I'm unsure if this will fix the problem. I also read about upgrading the can-bus. Which of these would be the fix to my problem before I start shelling out more for both? I'm to the point of just ripping the navi out. Any help would be appreciated. Thank you
