Bluetooth and USB port not working

[fgranville]

H All; I changed my 2009 E90 320d's battery on Friday. Now my phone doesn't want to connect with Bluetooth and the usb connection port in the glove box is also dead. Any body got an idea what could be wrong and how I could fix this. This car has Idrive.

Thanks

Sounds like the MULF in the boot gave up the ghost. Fault finding this a bit of a pain, although it's usually the actual module that bombs out. Common failure on these.

Check if the usb port in the armrest as well

apologies, the usb is located in the armrest

OK; Now also found out the NAV is not working either.

Nav greyed out or not finding your location?

Both the NAV and Telephone connection looks as if its loading

Hmmm, the loading of telephone is because your CIC isn't seeing the BT module. Not sure why Nav is messing around that way.
