Hello. My Dad and I are thinking of buying a car audio system for my Mum for Christmas. She's got a 2004 Peugeot 206. We think she'd like a system that will play music from her iPhone 4S, and allow her to take phone calls hand-free. Also it would be nice if the system would make it easier to use the iPhone as a sat-nav. And it would also be nice if the system could facilitate the iPhone being voice-controlled with the Siri feature. I'm doing my best web searching on the topic, and am currently thinking Halfords or possibly http://www.caraudiocentre.co.uk Does anyone have any advice or suggestions? For example, so far I've failed to find a good independent website that isn't trying to sell me something, where there's a good forum or some good independent advice. Thanks.
