it might well be possible that the bluetooth module is fried and needs replacing?

I'm pretty sure I was outside for well over an hour doing the phone alone. And it needed run through at least twice.

Given the size of the update, a pretty shocking time, but it's better than a fried module. Interestingly, my iPhone worked fine before and after :)

I do believe you need to progressively upgrade any module that doesn't jump straight away....

Yes, but then I need some software for the bluetooth thats between v700 and v900 ?

Assuming my disk files didn't work either then :)

You could always risk the 5150 disks...

I would be interested in trying this with mine if anyone has an earlier version for me to try
Happy to pay postage unless there's another way of getting them copied?

I linked the iphone to the car today and it worked and I made three perfect phone calls before getting home! :)
if I could get that to work every day like that I would be happy! Normally I get a few minutes and out blows out the BT connection and will only re connect when I have shut down and come back to the car later.
I have bee using an damn ear thingy but really miss the convenience of the BT setup :(
