J c B o i Z Posted January 17, 2006 Share Posted January 17, 2006 From what I understand, 06 RX330 have the version 4 for navi and IS250/350 have the new version 5. I've heard the IS resolution looks soooo much nicer and what not. Did they just upgrade the monitor so they get better resolution or is it software based? Also wondering if anyone has tried putting in the navi disk from the IS250/350 into an RX330 and will it work? Thanks in advance! Quote Link to comment Share on other sites More sharing options...
Rx330driver Posted January 17, 2006 Share Posted January 17, 2006 About putting the IS250/350 Cd into the rx, dont do it. lol. i dont remember why, but something like from then on, you wont be able to use anything less on that car because it auto upgrades to only use the newer CD. I think... Quote Link to comment Share on other sites More sharing options...
jb59 Posted January 18, 2006 Share Posted January 18, 2006 I recently purchased an 06 RX330 and for the Nav it is ver 05.1. Not sure about the exchange of disks but that sounds right. Quote Link to comment Share on other sites More sharing options...
