Hey, i was wondering if you can put the stock navigation after market into the Z? If so does anybody know where i can buy it? If not are there any suggestions for a good Navi that fits nicely for the car? Thanks for your help and sorry if this is a bother

 

O Btw i have an 06 Silverstone

 

Just look into some double dins radios with nav. Stock after the fact is not advised.

or look into a Kenwood GPS unit with a seperate LCD screen put into the cubby area.
