I'm having a hard time finding a white low mileage is350 for my mother with navigation

I have found a few without. How much does it cost and how hard is it to install the factory navigation after the fact?

And if anyone knows of a white is350 for sale in good shape below 75k miles let me know please!

Since the non-NAV 2IS models don't have the same connections, you'd be needing to purchase a custom harness to get the OEM NAV to work in it :

But the hardest part in removing the whole unit is removing the center vent piece. Everything else is cake!

That's an expensive wiring harness + navigation

Or

Buy aftermarket for less than 1K!
