Lexuses71 Posted March 16, 2013 Share Posted March 16, 2013 Anyone who has a Gen 2.5 LS400 like me have or had any problems with their Navi system? Not that I have so far, but my car is now 14 yrs old and I shudder to think what I would do if it went south all of a sudden. It contols so much stuff (GPS, Climate & sound). How long do these units last on average? And what do u do if yours dies? Junkyard seems the only option... Quote Link to comment Share on other sites More sharing options...
1990LS400 Posted March 16, 2013 Share Posted March 16, 2013 Yes, the 98-00 navigation sometimes dies - but might last "forever". One solution is to obtain the HVAC controller from a non-nav car (pretty cheap on eBay) and either install an aftermarket radio via an interface harness or a used standard Pioneer audio head unit for 98-00. The Nakamichi head unit is not compatible with the nav system audio amplifier or connectors. And of course you can go the salvage route and buy used nav components. Make sure that the nav ECU under the false floor on the right side of the trunk isn't getting wet from trunk lid seal failure! The nav unit in the dash isn't all you have to be concerned about.

Lexuses71 Posted March 17, 2013 Author Share Posted March 17, 2013 Thanks Jim. I will just hope that the unit holds up as long as I have the car. Not looking forward to replacing anything. Quote Link to comment Share on other sites More sharing options...
