I just purchased a 2001 Lexus RX300 with GPS. Can anyone tell me what's the latest and most up to date version of their GPS. Also, how much should I expect to pay for this? Is it available through any other source besides Lexus? Any consensus on whether an upgrade is worthwile for the Metro DC area?
From what I have read, the mapping software is easy to upgrade, just take out the old DVD and pop in the new one.....can someone please confirm?
thanks.
