can tideland or someone else make a sticky permanent thread that shows the different generations of toyota nav units and the correct discs that they need (the U numbers)?? thanks I've run at least 5 different searches and can't find a thread that shows the correct U numbers for gen 4
Re: need a nav disc sticky thread made The U number for the 2011 update is U26. Remember, For the 2004-2005 models, the Nav is Gen 4. For the 2006-2009 models, the Nav is Gen 5. The latest dataset is 11.1, out since this October. == The discs have multiple part numbers - so Toyota can sell as replacement part, loose part, etc. 10.1 (2010 update) Lexus part# 2004-2005 86271-GEN04-10 86271-48240 DVD U25 464210-1700 PT219-GEN04-10 2006-2009 86271-GEN05-10 86271-53025 DVD U35 464210-1711 PT219-GEN05-10 11.1 (2011 update) Lexus part# 2004-2005 86271-GEN04-11 86271-48241 DVD U26 464210-1900 PT219-GEN04-11 http://www.lexusnavigation.com/pdf_docs/Lexus-Nav-Quick-Ref-Sheet03102011215831.pdf shows the color coding of the dots on Toyota/Lexus nav DVDs.
