New to the group: needing help with Bluetooth stuff

[BillH]

Hi
I have a 2009 Tiguan and have replaced the Headset with a RCD510 model, and the bluetooth module with a 5K0035730D model.
Found you on line
Cheers

And you want to know what?????

Thanks for returning! I thought I had to do a sort of self-introduction before making enquiries/posts.

The main question relates to accessing SMS as they come through. I don't get an audio message everytime; when I do, the radio switches off, but the volume on the "you have received a message from X" is usually low; when asked to "read it", there is no response from the unit. (The microphone works fine for the phone in general.)

Nor can I generate a voice tag to use to call.

The star button does not appear to do anything.

But the phone book is good and keeps updating. The radio works well with 2 channels. The CD player is good. I can play music from my Windowsphone with some tweaking.

Am not sure how to progress from here. Is there some kind of firmware upgrade?

Thanks for any advice.
