Thanks for the tip and the offer of help IceBlue
I'm about 200 miles south of Glasgow and, though I do love driving the car, it's probably a wee bit too far to go just to test a cradle! lol
Very kind of you to offer though, thanks!
It's encouraging to know someone else has it working with the same phone though. I don't think it's bent pins since the adaptor is new and unused, but I'll check. I suspect someone's disconnected something when the parrot unit was installed. I'm gonna pop the unit out and take a look at the back when I get time.
