Hi.

the whole front of the unit flips down, you insert the Multi Gig double layer DVD, it covers the Continental USA and the largest Canadian cities. You can plug in an address or phone number of your destination and it guides you by map or just tells you where to turn. Points of Interest are built in like gas stations, malls stores car dealerships hospitals etc... It does not play regular DVDs. Too bad... Also, you can listen to a CD while the nav system is on the two bays are independant. I love the system.
