I have a HSE that missed out on SATNAV. Had a Quote of about $4000 to intergrate factory unit. Major problem first is that car has to be rewired. No wiring from rear of car to head unit. BIG BIG job. Unless SAT NAV is already there not worth the money. A cheap NAVMAN/GARMIN etc will have better maps anyway.
Make sure front has had recall done. Look after the auto but then Gavin could tell you of his tale of woo.
Start driving a few and enjoy . You wont go back to anything else.
