Hi, I'm offering a supply and installation service of RNS-E DVD based sat nav systems for A3, A4, A6 and D2 chasis A8/S8 cars. I carry stock of HU's, TV tuners and all the bits to fit them to standard double din cars. I will not be offering facia ugrades. Standard installation including 12 months warranty is £1000 and that will include the latest 2005 DVD, all wiring for CD changer/telephone and BOSE where applicable. VAG coding included for your car to match tyres, etc. TV upgrades areavailable for existing TV installs when upgrading to RNS-E at a reasonable cost. Upgrade your CD based sat nav to DVD based, older pre 2002 cars can be done, but with a few caveats regarding DIS and clusters. PM me for details.
