I want to install the OEM navigation in my 2010 IS250. The part number I am looking at is 86431-53330. I am hoping someone can confirm that is the correct part number I need and if there is a pre built harness I can use for installation. Thank you.

 

lexuspartsnow.com has this adapter 86842-53030. Possibly what I'm looking for maybe?

 

So I am being told by my local dealership and car audio stores this is not possible. That being said what is my best option for an aftermarket Nav the looks as close to stock as possible? Im not a fan of the units installed down low in place of the CD changer.

 

I have a 2008 I am actually interested in this aswell.
