The official tablet (and other useless electronics) thread!

[Ryan T]

I'm not sure if this has been touched on in the useless electronics thread, but I'm in the market for a navigation system. I can't find one that will go into the dash of my silverado and keep the cd player and such without upgrading to a 2003 bezel and a/c controls. I'd be fine with an externally mounted one. We've been using the navi on sam's smartphone during our honeymoon and it blows donkeynuts. My mom has a garmin that is a couple years old, but has technology on these advanced much in recent times? Is picking up a year or so old unit worthwhile? I'm completely out of touch with technology when it comes to navi.
