Hi, Can anyone help. Just about to go for the dension 300 as it seems quite expandable i.e usb etc. However not 100% sure if I've got a concert or concert gen2 + which are the options on this site: http://www.ipodcarkitdirect.co.uk/i..._Car_Kit/Dension_ice>Link_Gateway_300_Car_Kit My head unit just says concert. Its an A3 55 plate would that determine it? Also any thoughts on the dension kits would be appreciated! Cheers in advance.
