Just got myself a lovely 2002 RX300 and love it, second Lexus I've owned after a 1996 LS400 which I loved.
The satnav does work but it's an old version, can it be updated to a later maps version. The guy who I bought it off gave me 2 later version maps dvd's but said he couldn't get them to load or read them. Is there anything I can do and what's latest version of maps I can use. Thanks guys.
