Hi all Yesterday I had a new pioneer SPH-DA230 DAB+ headunit fitted to my 2011 A3 by DynamicSounds. It's a black edition will full bose set up. I had it fitted as I didn't feel comfortable doing it myself and didn't want to be without a radio if things went wrong... however still got a few issues. It was fitted with this kit from dynamic sounds: https://www.dynamicsounds.co.uk/aud...scia-steering-bose-retention-fitting-kit.html I'm currently experiencing 2 problems, that I hoped someone with more knowledge might be able to help with! 1. Iphone connection creating static - The primary reason I wanted the head unit was for Apple Carplay. However, when plugging in my iphone 8 via a lightning cable to the usb adapater, I suddenly get a large amount of interference/static through the speakers, which is really making it unusable as I can hear it over any music/radio played. The static stops when removing the phone from the cable. I've tried a different lightning cable and phone both with no difference. Anyone know what is causing this? As I understand it the SPH DA-230 only has 1 usb connection in the back, so I can't try another usb port. 2. DAB radio is a bit patchy (probably due to the location I live and the internal glass mounted aerial) - I can live with the fact that DAB won't be perfect and wasn't expecting it to - but my FM radio is currently worse than it was before. From a bit of research, it looks as if the fitting kit bundle might have used been a single fakra to single din adapter for the FM aerial? But my if my car is a 2011, it probably has the dual fakra connection? If I swapped it for the following adapter... would it help the FM signal? https://www.dynamicsounds.co.uk/connects2-ct27aa86-universal-twin-fakra-to-iso-antenna-adaptor.html I'd really appreciate any input as my knowledge around this is very limited! This is the first time ever changing a headunit. Thanks!
