Is it possible to install a factory navigation system in a non-nav Lexus? Is the only difference between the two models the stereo unit itself, or is the wiring harness different as well?

 

from what i was told everything is different. i wanted to put a non NAV unit in mine. but someone said it would be easier to sell my car & buy another that didn't have the NAV. probably better off just looking into aftermarket options.

 

The original nav is laughably outdated, it's tech going on 20 years old in design at this point. Any cheap Garmin makes it look terrible. Why not just go for aftermarket? I deliberately went for a non-nav for that reason.

Pioneer has 7" touchscreen models for $300 that have CarPlay and Android Auto support, and you put them in with the BeatSonic bezel and steering wheel control interface kit. It's going to be a spring project for me, I was just waiting to see if they came out with new models with Alexa integration as well.

 

I dunno how easy/hard the process is, but do not do it. The factory nav is obviously an old system, and most importantly, the map can not be updated. I have a 7 inch Garmin with lifetime map update which is awesome imo.

 

Good to know about the factory nav. The beat sonic bezel would work; I was just hoping to preserve the contour of the original dash, and the beatsonic bezel is just so darn clunky looking.

 

Really? That seems laughably shortsighted on Lexus' part . I guess they figured no roads would be built after 2005.

 

Lexus used to release navigation updates on a DVD each year in the third quarter. I don't know if they still put out updates for the LS 430 units though.

 

I would really be interested in understanding how to switch from NAV to non-nav! In my search for an LS I really wanted a non-nav model but beggars cant be choosers especially when you find the right specimen that meets all the priority criteria. I don't care about a backup camera either they make me dizzy lol.

 

Be glad you don't have Navigation. I wish my 2004 was a non-nav model. The 20 year old navigation system is completely worthless in 2024

 

The Grom unit actually brings the factory navigation into 2024.

 

I purchased a unit from aliexpress that replaces the factory nav with a 9 inch screen that looks like factory installed and is basically an android tablet with usb ports and data capability as well as back up camera and radio. Very easy to install and not too expensive.

 

I actually like this, it keeps the stock look. I know resolution is a little bit of an issue. Lets hope someone comes up with a replacement screen with higher resolution

 

Mine has the Qled 1280/720 9 inch screen but do loose all the side buttons and everything still works.

 

Ya that's cool but I'm not a fan. That's why I would have preferred the non-nav edition. This way you get the factory climate controls plus an updated double din head unit which looks really good with the appropriate bracket. I'm serious that I would consider swapping out my NAV for a non-NAV to get the climate controls if someone could provide the appropriate instructions

 

Just to give you an idea how mine looks.
