I have an 05 STS, but it has the bose 6 disc and not the Nav system. I'm curious if I can buy the Nav radio off of ebay or seomthing like that, and just install it in the dash? I guess the questions would be, does it have all the needed components already installed, but just needs the nav system plugged in.

Let me know if anyone has tried this, and if it works, and what all I would need to do.

Thanks,

 

No, dont even try it. It is not a plug and play system.If you want a NAV system you will need to get a stand alone system.

 

ok, that answers that question. thanks for the quick reply.
