Still cant believe I didn't cop it, nice little bonus. I'll eventually get a combox for it but if I remember correctly audio quality is better via USB anyway. USB issue I had was a red herring, for some reason the CIC doesn't like the 64gb Sandisk drives I was testing with (both fat32), I stuck in a 16gb drive and all is good . I just need handsfree working more than anything else at the moment.
Put in a big order of parts last night so hopefully will have the car fully sorted in a couple of weeks. Most of its overkill but sure no point replacing 13 year old suspension components piecemeal, must get a thread up on it.
