Just had a new Alpine 103BT fitted today, although most people said it's better to have a seperate parrot, I think it's excellent!
Had a few problems! - When I brought the car it had an aftermarket stereo, BUT had a receipt for professional fitting by a company, I'm guessing Halfords now (so professional is out of the window!) and turns out that they majorly screwed up the wiring!! Now the stereo is fitted properly, although it cost more for the company to sort it out, the radio is still a little dodgy, it's got the proper amp'ed ariel cable, but doesn't pick up many stations!! Put a standard (test) ariel in, and all works fine! They said it can be one of two things the thacker(?) connector on the loom or the cable itself! Not sure if you can buy the ariel cable from Audi as it's all part of the loom! or whether you can buy this connector as all the connector books that the stereo company had don't list it!
They have suggested cutting off the standard connector, and making up a different cable to check. But I don't really know what to do from here! the stereo is awesome, but the radio sucks!
