2cmorgan Posted June 5, 2018 Share Posted June 5, 2018 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. Quote Link to comment Share on other sites More sharing options...
1990LS400 Posted June 6, 2018 Share Posted June 6, 2018 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. Quote Link to comment Share on other sites More sharing options...
