stoodo Posted February 20, 2010 Share Posted February 20, 2010 I Installed a Nav from 2005 ES330 in My 2003 ES300 that had Nav / ML. Everything is working great except for the CD changer. (The plug seems to be different) Also there are no voice prompts. I've seen rumblings of needing a separate amp? Has anyone else down this upgrade before? thanks!

stoodo Posted February 20, 2010 Author Share Posted February 20, 2010 Anyone have pinouts for the 2003 nav or the 2005 nav? Thanks! Quote Link to comment Share on other sites More sharing options...
SW03ES Posted February 20, 2010 Share Posted February 20, 2010 Quick question....why? I have both systems, the newer one in our 04 Prius and the previous one in the ES300...I much prefer the previous system. Quote Link to comment Share on other sites More sharing options...
stoodo Posted February 21, 2010 Author Share Posted February 21, 2010 The Gen 3 system seemed VERY dated, while the Gen 4 system seems only somewhat dated. I just liked the look of the Gen 4 better. I have a Gen 5 in my Prius and the Gen 4 is more reminiscent of that. The sound quality of the Gen 4 seems vastly superior over the Gen 3 head unit. (IMO) I found the answer to my own question about the CD changer. Apparently you need this adapter to plug in the old style CD changer plug to the new style.

SW03ES Posted February 21, 2010 Share Posted February 21, 2010 Really? To each their own I guess. I think the display of the Gen 3 system is smoother and crisper looking than the Gen 4 system... Quote Link to comment Share on other sites More sharing options...
dario Posted February 28, 2010 Share Posted February 28, 2010 I never like OEM navi units so I opted not to pay $2000 as a dealer option on 2002 Lexus ES300 so I installed Pioneer navi unit. Much better got it bypased and you can watch DVD movies on it plus XM radio and bluetooth option. Quote Link to comment Share on other sites More sharing options...
