I have to give my two cents on retrofits. I also did not purchase my unit from Patryk. My unit was advertised as having the latest software, US Maps loaded and was suppose to come with the 6NR coding so that I could add the combo box.
I received the unit and it was an easy install. Of course I did not want to cut my wood grain for the new controller, so I kept the original controller. The first issue I noticed, as noted before was there was no sound. The more I played with the unit, I found out that I did not have US maps installed. This made me worry if I did have the 6NR coding at all. I went back and forth with the seller (I will not name) and was sent to Patryk@bimmer-tech (www.bimmer-tech.net
) for help and coding.
Patryk did not have to help me as I did not purchase the unit from him. Once I received the DCAN cable, Patryk graciously contacted me via skype on a Saturday morning. I downloaded the files and programs that was recommended and he went to work. We quickly noticed that my software was not up to date as advertised (it was from 2009) and the maps were 2008 and from Europe. So my navigation will not be active until I get the proper maps installed.
He was able to get the sound on in seconds. He also got the Ipod and Sirius running without any issues. He even worked his majic on the old idrive controller and it works perfectlly. My next step is to add the new climate controls and I will be sending the unit to him to load the proper maps and to code it for the 6NR to allow me to use the combo box (that I will purchase from him).
Guys please do not go with any other venders. You will end up dealing with Patryk anyway. It just makes sense to pay a little more and purchase from the pros who started this process. Most of the venders will sell the units but they do not have a clue on the coding.
I have learned my lession . Do not make the same MISTAKE!!!
