Hi guys I'm a new member just bought a lexus gs300 2004 it has no satnav so I've bought a factory satnav from ebay but needed to ask I'd anybody csn advise me. I've just got the screen and not the box which I think fits in the boot . I have seen a one on ebay but I thinks it from a 97 model lexus gs 300 could that work on my 2004 model also can this be done and of so any recommendations of garages who can do this job. Look forward to any replies thanks guys.
