Quick one, am I right in thinking that there are two radios/sat nav units for the car. The Nav trim has the basic version, which is easily identified as having the USB socket on the screen fascia. The Lux/Cup trims have the better version (R-Link?) which has SD and USB sockets down in front of the gear stick. Sorry for a daft question, downloaded the brochure from 2013 and 2014 and thought I had it sussed, then saw what was listed as a LUX for sale, that seemed to have what I thought was the lesser radio with USB by the screen. Thanks!
