Retrofit DAB+
Hi,
can someone tell me what is needed for a DAB+ retrofit (E92)? I know that I have to replace the head unit with a DAB-tuner-integrated one and code it. What else do I need? I read through several threads here today, and couldn't pick up all necessary information for me. - Do I need to replace the rear window? - Do I need a DAB antenna? Which one? A new one, or can I use the standard radio antenna for DAB too? - Cables? - Diversity? Do I need a new one? Or can I connect an antenna directly to the DAB ports on the CIC HU? I don't want the aftermarket kits like Kufatec. Want to have this completely oem-integrated in the CIC. Thank you. |

DAB CIC (very rare but do come up, i have one and cost me around £500) DAB diversity antenna (again very rare but do come up) 5m (i think 3 was too short) fakra cable that goes from diversity antenna to CIC simple bit of coding and away you go. you will need to 'activate' the CIC for sat nav but this can be done with scripts these days, when i did mine i used an emulator. a |

Thank you Josh! Activating the CIC is no problem, have done this on my current CIC for the other functions.
I still don't unterstand the function of this Diversity Antenna. Is this an antenna or a ECU in that all antennas are pluggin in? |

for dab l-band reception you have to replace shark fin antenna and route wire to it also there is such lifehack as to use cabrio iii-band antenna which is located in rear bumper you can install such iii-band antenna in any bmw

If so, I just need to replace the diversity, so I have an additional output-connector from diversity->to CIC for dab? Quote:
Is this cabrio antenna for iii-band or l-band? Or both? Can I install this somewhere else? And do I need to replace the diversity for this option? |

http://forums.m3cutters.co.uk/showthread.php?t=49259 it’s a shame the pictures are no longer there. the diversity antenna gives you a DAB output from your sharkfin, you then run a cable from the diversity antenna to the CIC and code. The diversity antenna is located at the back of the car behind the rear window brake light cover. |

Thank you and sorry for asking again, but I still don't understand everything and I want to go sure before buying things:
You said: version 1: - I can use the FM antenna for dab iii-band with changing the antenna diversity so I get an additional fakra output connector for connecting diversity ->to CIC. or version 2: - I can use the cabrio antenna without having to change the antenna diversity, so connecting directly the cabrio antenna to CIC with a fakra cable? But, if I understood right.. both solutions are for dab iii-band. What about the l-band, when there is no sharkin? I attached a picture of my diversity. Is it really just plug&play? Or do I have to change something on the wiring from diversity to FM antenna? |

Okay, so the original parts from cabrio are
- 65209123784 for l-band and - 65209123995 for iii-band. So I could use both and connect them directly to the CIC headunit. Or I could buy a new diversity with dab output and use the FM antenna for iii-band, then I would need the l-band antenna 65209123784 separately. Can I connect it directly to the CIC headunit? Or is this connected to the diversity, too? I just read a little bit about the kufatec DAB retrofit kit. In the set there is only one antenna. I don't know if for iii-band or l-band? Or does this antenna covers both bands? Is there a way using this antenna with CIC headunit, without the kufatec ECU? Maybe I could use it and connect it directly to CIC. |

i believe that kufatec antenna is iii-band, since it is active you can also use it with cic i think
the reception level will be worse i think you can buy new diversity amp with dab and then connect it using additional wire to cic equipped input for iii-band signal

Okay and just to be sure: I don't have to change the wiring from diversity to FM antenna in window or something like that? Really just change diversity, plug the existing cable coming from the window in the new diversity, and going with a new seperate cable to the CIC dab-iii input?
