Here's the deck I'm looking to get shortly...

I was wondering... Are there any navigation systems that I can plug into that and hide possibly? My friend bought a GPS for his laptop for like $125 or something and works really well. But I'd like something for this. Now mind you this head unit is not touch screen so it'd have to be remote controlled or something. Is there anything? I'm not too familiar with the GPS market these days.

...i dont want a seperate screen for the GPS is all.

I'm not a fan of using my 650 for navigation.
