I've got a 2010 ZDX base version and one of the main reasons that I have not opted for the tech pkg is that it cannot play DVD's. I thought I could get an after market in-dash nav system that's touch screen and capable of playing DVDs.

I could not find one out in the market yet...I was wondering if anybody knew or have any idea if there's any compatible after market in-dash GPS available for 2010 ZDX base.
I'd settle with just an in-dash Nav system even if it's not a touch screen or doesn't play DVD.

Can someone please let me know, if there are any options at all??
