Hello, I have 1998 year GS300 with navigation and it has CD.




And i do not know what is the version of this navigation and where I can download europe maps, because if I take CD off it does not gives MENU option.

and I have question is there any guidance or psibilites to change navigation main head units to 01-05, as I can see it is different plugs but maybe with prober wiring is posibility to change from this



to this
