I just purchased a GS300 without navi but really regret and want to put in a navi system. anyone know if there are OEM navi available for purchase? also, would like the ML too if possible. any other ideas? in-dash aftermarket Navi? Portable GPS?? Thanks in advance

 

You will not be able to go OEM. If you want OEM your best bet is to see if you can find another car with ML/Navi and buy it and sell your car. I would just go portable.

is the screen not compatible with the remote mount GPS navi?

as portable goes, i had a Garmin unit before, and i really liked it.. only if you don't mind putting it on windshield..

 

anything is possible with money but honestly added oem nav will cost so much it's not worth it at all. just get an aftermarket
