I bought my car without one thing the navigation system. Is it possible to install a navigation system on my Lexus? How much? Is it hard? Any other ideas for that area? Thanks for the help!

 

Well...Lexus will not install their navigation system on an IS that did not come from the factory with one originally.

So you have two options. You can either buy an aftermarket screen/navagation setup (probably your best bet)

OR

You can buy many of the parts from Lexus like the screen, motor, wiring, etc. and try and build the nav system yourself and keep it looking stock....however...this becomes pricy ...

so you might as well get an aftermarket one so u can get a better nav system and larger screen.

Just my opinion.

 

you can get an aftermarket one, it's about 2k, but it won't look that "stock"

and forget about doing a stock nav swap, it would cost you so much it's not worth it

 

Here's a good compromise -- stock NAV screen with aftermarket NAV system.

It still won't be cheap though.

 

Sleepy,
That looks very clean, looks like it came with the car! Any idea how much that runs? Who did the work?

 

Well that's not my car, and I'm in no way related to the poster, so you might want to head over to is300.net and ask the poster directly. I believe there are instructions on how to build the factory NAV housing if you follow the links.

 

around 3k for a good install imho
