Would the RetroFit Nav Unit work just for Radio and OBC? I dont want it for GPS/Nav
I did a search that led me to over 50 pages of info and 20 various threads that did not answer my quest and left me slightly more confused.
Most of you get the Nav Retrofit for the GPS function. I already have a 2009 Tom Tom Go 730 in my car and don't require a dinosaur OEM GPS unit, but I do like the Nav for aesthetics and to get the CD/Radio/OBC/Alarm functions coded on one interface.
Can I just install the Head Unit (like if it was another radio head unit) in the dash and code it at the dealership and get all the other functions to work?
...or do I NEED the entire kit installed to get just the CD/Radio working?
marti are you sure about that? Navi sends the RGB (red green blue) video signals to the screen. Without the Navi the screen should not work unless you have a factory video module which is supplying the signals. Also you will be removing your factory radio from the dash and need to buy a cd43 radio or BM53 which mounts in the LR corner of the trunk.
I see now you said your TV still works. This is why you still have a screen. because you have the TV option your video module is still suplying the screen with the correct RGB signals. He would have to buy either a Navi module or a Video module to power the screen. DelMarco, if your going with the 16:9 wide screen then the navi module is probably cheaper. If you're going with the 4:3 screen thenyou can prob get a video module cheaper.
I have a 97 740i with a radio that comes on sporadically at full volume and then goes off. I've talked to bestbuy and they want me to put in an amplifier bypass with the new radio. Is this really necessary with a 56w 4channel output?
