I have recently purchased a 2009 Passat with an RCD 510 Radio. The car does have a bluetooth module installed and I have worked out that the unit is a 9w2.

However, no matter what I do I cannot get my iPhone (or another older samsung phone I have tested) to see the car's bluetooth. It seems to just not be there...

The 'Phone' button on the radio just functions as a mute button at the moment. Is this because there are no phones paired, or does this point to a more serious problem?

Short of assuming the BT module is just completely faulty and swapping it out, is there anything else I can do to diagnose the problem?

Might be that it's just not compatible. Some of the older Bluetooth modules simply won't talk to a modern handset like the iPhone.

Have you tried playing around with the options in the MFD trip computer? That's the other place to look if you're not seeing any menus/ settings in the RCD.

Unfortunately this is right. The early (pre-2011) VW factory bluetooth units use the rSAP profile, so won't communicate with Android or iPhone. The later modules are available on eBay and can be fitted quite easily (the module is located under the driver's seat and held in place by Velcro) but may need coding to the individual vehicle.

There are also some paid apps around for Android that can convert the bluetooth profile of the phone to work with the existing rSAP module. I don't know how good these are and I'm not sure if any such apps exist for iPhone.

Thanks for the information.

I have a 9w2 module which is meant to support A2DP for music streaming. I would have expected this to work at least. What Bluetooth standard am I missing?

What module do I need to replace it with in Europe? I have seen a lot online about the 9w7 module being the right choice, but this seems to be a North American module. Is there a difference?

I've got the 9W7 module in my Golf and it works well. Talks to my iPhone 5 and is able to do music streaming, calls and phone book access. Car originally had an RCD 510 and that worked fine with this module
