I recently purchased the navigation screen, ECM, and GPS antenna for my 1998 LS400. For what I understood the LS400 is pre-wired for the NAV system. Mine came stock with the standard setup (pioneer head unit, climate control, and CD changer). Is it possible to upgrade my LS to NAV, because if so I don't see the connectors I'm supposed to plug into the system. I've spent a good bit of money on these parts and now I'm fearing I can't use them. Any help would be greatly appreciated. Thanks !!! :(

:o You will not be able to install the nav without a custom made wiring harness. There are no aftermarket solutions. Whoever told you that the car was prewired for nav from the factory owes you an explanation BIG TIME !!! <_< I may be able to get a wiring harness for you. If I may ask... How much have you paid for the system so far ? And exactly what parts have you purchased ? Can you get your money back ?

Thanks for responding !!! I have spent around $750+ for the navigation screen, navigation ECM, GPS antenna, and navigation owner manuals... and unfortunately I don't think I can get my money back... I'm at a lost right as I don't know where to go next... If you have a custom wiring harness or know where I could purchase one I would appreciate it... I'm taking Electronics in college, so I have the ability to understand the wiring and componet part I just don't know what are my options, unfortunately if any... again, thanks for taking the time to reply !!! :(

I'll look into it, Usually the harness is sold as part of the complete system.
