Retrofit Garmin Navi
Anybody fitted one of these?
From what I gather you cannot just buy and install the bracket and buy your own Navi as it has to have the BMW software Don't suppose it shows the parking display same as factory? |

Yes, I have a "BMW Navigation Portable Plus" (2nd generation, 2010 = Garmin 765) in my E89, but I had my dealership mount the device.

BTW: If you are interested in retrofit navigation, you might want to have a deeper look into the new 4th gen. "BMW Navigation Portable HD Traffic" (see here - sorry, German only) - this device is based on the 5-inch "Tomtom Go Live" (probably model 1015?) instead of Garmin and has its own realtime traffic information OTA. I am also looking for an upgrade at the moment (but I am a bit hesitating as I have no information on handsfree set quality - the handsfree set of the 2nd gen Garmin portable plus has been much better than all other successors due to a 2-microphone array).

Thanks that's great Do you think it is just the cars software that needs changing s it plays sound through the speakers and not the actual Garmin? In other words now its done can you add any Garmin unit off the shelf? Hope so as this would allow future upgrades and mean I could just have the car kit and buy my own Nav Any chance you could try another stock Garmin unit as a test?

You're welcome

Maybe there is another option: As soon as the car and your radio are coded for usage with the BMW navigation portable plus/pro/HD traffic, the signals on the referring cables of the cradle should be transferred between radio and navigation device - in particular "Signal Mute" and "NF GND" / "NF R" for the navigation commands. So if you find any navigation device on the market that has its own cradle and is capable to generate such signals, you might perhaps install BMW's cradle, have some dealership code car and radio for use with this cradle and change that cradle for your new device's own cradle. Please find attached an excerpt of the installation guide for the BMW E90 series (sorry again only in German). You will find the connection scheme that should allow to attach any other navigation device to the cables that accepts a 12V power supply (signal "31" = Ground, signal "15" = ignition 12V+), that has a signal output for the speakers ("NF GND", "NF R") and an output for a "mute" signal. BTW: Tomtom's HD Traffic (= go live 1015) appears to be quite rubbish, so I will probably stick to my old 2nd gen Garmin navigation plus...

Pity it's not simple but I like your thinking.
So bmw have added something to the software to stop you adding your own Garmin and therefore an updated model when it arrives Looking a the diagrams you kindly posted, assuming all garmins output the necessary signals, then it should be possible to rearrange the b1-b12 connections if they are not in the correct order? |

Does anyone have a picture of what the Portable Navigation Plus looks like installed in a Z4? I've done a Google image search and all I could find are installs in 3 series or 1 series.
