Not pissed or preaching simply saying given the cost of the kit one would have to pay to have this fitted to a new car what I was asking wasn't unreasonable. After all I'm sure the dealer would bump the price up a few hundred simply because the kits there.
It's actually fitted with a serial code which is unique to the car never mind the model so it would be pretty useless in another vehicle unless Fiat were prepared to change the code.
Point is I think the unit is worth £500 on the used market whether someone's prepared to pay it or attempt to fit it is their choice. Of course the last two posters have valid points and unfortunately the residue value of Fiat is pretty poor any how so I only have myself to blame for buying the car from a Fiat dealer and paying top dollar.
By the way Jimboy that's a lions roar you should spend more time in the jungle.
