Anyone convert non navigation to navigation?

I have '07 GS350 thinking of adding navigation has anyone done this? Try to do OEM. I'm new on this forum and sorry I know this question as probably been asked several times.

Back in the 2000's there were one or two members that supplied navigation system components from salvaged vehicles for retrofitting navigation into vehicles that didn't come with nav.  It's been a long time since I've seen them active on this forum.

Your GS is 11 years old.  Is it cost effective to retrofit OEM navigation into a car that old?  If you need nav, maybe you could use a phone based nav app or a portable GPS such as one from Garmin.  An OEM nav system from 2007 would likely be considered obsolete.  If you have to have in-dash nav, maybe consider an aftermarket nav product.
