Dave Rose Posted April 10, 2019 Share Posted April 10, 2019 (edited) Hello, I have an RX300 SE NAV 2004 and need to update maps but have problems finding newer version discs. I have noticed other Lexus owners with Generation 1 units replacing these to get newer map updates. Has any RX owners tried this? Thanks, Sorry but forgot to mention I am in the UK and the RX300's were made up until at least 2006 but your titles only went to 2003 for the 300. You seem to be a bit more experimental in the USA so I thought I would take a chance on asking.# Edited April 10, 2019 by Dave Rose Left out vital info.
