The best upgrade I must have done to my RR was to convert the sat nav system from the old cd to the new DVD sysytem, makes the sat nav in 3D brilliant also got speed cameras! full colour and also 7 digit post codes. Just buy new DVD model & plug & play. you will need to get 2008 disc and you are rockin.I also got TV in motion done for £50, i got the whole deal done fron a local guy, (off coarse I dont watch TV while I drive my wife does!) ITS A MUST DO UPGRADE!!
