Thanks for the instructions and pictures. I put everything without the fan but I will make it a point not to use the nav until I fix the fan. Actually I cannot use the nav because it is stuck on another state when i try to use it. I'm surprised it showed up because I thought the whole nav part did not show up until the vehicle was coded. speaking of coding the dealer is gonna charge me $280 but he isn't sure that it will work. he claims he cannot change the VO but he will try something else. If only I was patient enough to wait and get a cable myself . .. .
