Funnily enough I called at my local dealer today after speaking to them about it last week. Last week they verbally quoted me £299 inclusive of fitting for either the iPod connection or the USB / 6FL retrofit and confirmed both wre same price. As I only have the AUX connection and I don't want a glovebox solution - I want to use the front armrest, I decided on the USB retrofit. Went today to book it in, confirmed price - £299 as they previously told me, so booked it in to have it done on Friday
. 1/2 hour later they phoned me to say the USB retrofit wasn't £299 but £900 instead. WTF. They insisted theat's what they quoted me previously but it wasn't.
