Hi guys~

I want the Navigation system of 07 so I just wonder that if I put the Navigation CD of 07 GS to my 06 GS300, it will be working?

 

If you're talking about the upgraded resolution of the Gen 5 nav, then the answer is no, unless you're willing to spend an exorbitant amount of money on the new head unit. The '07 DVD will not give you the better graphics you're looking for.

 

If you load a 07 DVD into your 06, you might end up upgrading the firmware. If that happens, you will loose the bypass. (menu. volume. left up..left down....etc) There are other info posted here.
