Hi guys, I just had a friend in the trade fit one and it works off the stereo buttons straight away and sound quality is great but only the up and down buttons for volume work off the steering wheel. The central display on the clocks just says phone but when I called the car my name comes up on the stereo display from my mates phonebook as he leaned his phone in to test it. My question is do I need the star machine to turn the full steering wheel/phone functionality on? Also does the clock display panel need the same? Anybody know or have one? Regards,Andy.
