David Anderson Posted February 10, 2012 Share Posted February 10, 2012 I have a stock '99 LS400 with a Nakamichi radio and without navigation. Was wondering if I can put a factory unit in and is it just a plug and play or are there wiring issues? Thanks for any iinfo. Quote Link to comment Share on other sites More sharing options...
1990LS400 Posted February 10, 2012 Share Posted February 10, 2012 What factory unit? The one from the 98-00 LS400 which is quite pathetic? If that is what you want you would have a whole lot of wiring to do. The 98-00 LS400 without nav is not cabled for nav. And the 98-00 Nav audio functions are not compatible with the Nakamichi but is compatible with the standard Pioneer system. The Nakimichi has a very different architecture from the standard Pioneer and the audio portion of the 98-00 navigation system which are largly if not completely compatible. For hundred bucks you could buy a Garmin that would head and shoulders above all but the latest Lexus nav system. Here is a photo of how I mounted a portable nav in my 00 LS: http://us.lexusowner...leryℑ=1349 Quote Link to comment Share on other sites More sharing options...
David Anderson Posted February 11, 2012 Author Share Posted February 11, 2012 Thanks for the info and the pic. I have a Garmin that I am going to use and mount somewhere. I love the garmins but like the look of the in dash unit. Quote Link to comment Share on other sites More sharing options...

David, I will look into this and find out which is the latest system and map that would work in your 99LS. Quote Link to comment Share on other sites More sharing options...

If you really want a "captive" GPS/Nav system a car trade would be more appropriate. Quote Link to comment Share on other sites More sharing options...
