Dealer won't install it
Hello em2023,<br> <br> The dealer never thought it was possible to retrofit so they never ask to do it. My service techs were very helpful in pointing out want not to do and provide technical hints. I guess they don't do anything unless is published in the MB bulletin. My car is a 2002 E55 and I was concern about the warranty also. So I took the precaution of not irreversibly altering anything when I tested my Comand 2.0 initially. I only proceed with the installation once I determine everything is working properly. I did extensive research on wiring schematic/ layout and on information I obtained on the internet. There are only 5 wires to modify and I work on 1 wire at a time to prevent any chance of shorting the circuit. If you are not comfortable cutting the wires ask the dealer tech to do this( my tech decline). Make sure you have all the parts ready. You don't want any loose wires while you waiting for parts to come. All the wires are color coded and it is standardized between the radio and the Comand units. The biggest hassle will be installing the reinforcement/ mounting unit. This should be your biggest headache. I recommend to let a Mercedes authorized body shop do this.<br> <br> Since I bought my unit over the ebay, in Germany, there is no warranty with the unit. If it malfunction, it will have to send to a Blaunpunkt/Bosch service station. Now if you acquire the unit from the dealer, then it should come with warranty. But the cost for a Command 2.0 is $6000 according to my dealer. With that money I can buy at least 7 Comand units from ebay. You should consult with Frank, the moderator. He has just installed a ML-class navigation unit into his CLK and he is very knowledgable. I ask him for help and advice frequently. If you are able to obtain a US version of Comand 2.0, go for it. It will a lot cheaper than trading your car in for a new car with Comand 2.0. <br> <br> John J
