2009 Sport nav Bluetooth Module fault
« on: December 19, 2017, 04:17:07 PM »
Hi,
The Bluetooth no longer works. It will allow me to go into the pairing menu and try to pair but will not pair with either an iPhone or windows based phone. Been told at the dealers that the module needs to be replaced but I'm sceptical as this is the usual response to all questions and they want £500.

I've read you can reset the module if you take the battery off, switch the lights on, and depress the brake pedal for 1 minute.
Q1 - Is this true?
Q2 - Is it likely to work?
Q3 - If I get a replacement (say from ebay) will just replacing the unit work? (i.e. no special re-programming required).

Hope there is someone who can shed some light on it.

Not sure about the 'process' if you disconnect the battery the lights (and the bcm that controls them) aren't going to work anyway.. I imagine its variation on the old "disconnect the battery for 24hrs" used to attempt to clear fault codes. Possibly worth a shot. Not sure if all the radios components are coded to each other though.

You can get a very nice touch screen bluetooth, DAB and Apple car play enabled head unit with a 4 x 50 output for 300 up. If it ends up with replacement I'd tear it down and go aftermarket and future proof while I'm on personally

The original unit has very limited handsfree capability with modern phones. Unless you have successfully paired those specific phones previously I suggest you check here to see if they are compatible:

Thanks for the replies chaps.

The iphone has worked up until the middle of last week.

To be honest the bluetooth system has a whole isn't the best, not by todays standard or indeed back in the day. Other cars of similar age had much better systems. (The bluetooth and Nav let the car down IMO). Other than that the 3 is a great bit of kit (never let me down in 4.5 years).

I really like the Sport but it's taken them an age to get DAB into a 3.

I don't know whether to chance it and buy a BDA 4 66 DHXA module and see if I can swap it, or clip a cheap thing to the sun visor.
