I'm after something like the Kensington LiquidAUX to work in my car. I just had an email reply from Kensington Europe saying that the LiquidAUX is not meant to work with iOS4 and so is 'not compatible' (although it can work, I believe there is a buzzing sound?) EDIT: I checked the email again and the product code that was included in the reply was for a Kensington iPod charger! The stupid support rep didn't appear to know what I was talking about when I said 'LiquidAUX'... I've been told that sound quality is better through the dock connector, so I'm just looking for something that can charge my iPhone 3GS and has an AUX cable from the dock connector. I've come across the Griffin AutoPilot, but basically just want opinions on what's best. Any recommendations or alternative setups would really be appreciated.
