Hello CL members I love the feedback from everybody on here ya'll help me out alot but i need ya'll help once again.I have a 2003 gs300 with a stock radio system i wanted to know if I can change or possibly switch that to the 2001-2005 navigtion system or is that even possible, if anyone knows how much it is to do that or have any information regarding this please help me out.Thankyou

 

i think there is a post about this but i'm not to sure. i think the problem u might run into is the wire harness might be different. either go aftermarket or handheld gps.
