Thanks M13KYF, you guys seem to reply at the spead of light!! I am impressed.
Yes, I was aware of that thread, unfortunately it doesn't resolve my problem though: I have what you guys refer to as the cradle (shoe?) into which slides the module photographed. I have an assembly very similar to that shown here: www.google.co.uk/products/catalog?num=2 ... EEQ8wIwAw# (sorry about that string). The assembly fits the shoe OK and has a phone cradle on the upper surface but I cant pair with my Nokia. I have also downloaded the user manual for the THB Bury assembly and this infers that they may be handset specific, but that isn't clear/certain.
Judging by this thread ianp had a similar issue. I am happy to buy the module photographed if it is 'general purpose', but wanted to be sure that it was my module that was incompatable and not a fault on my car. I guess the only sure way to find a local zed owner and see if I can borrow their module for a few minutes.
