I couldn't figure out, through the thousands of Nav DVD threads. But do you have to leave the Nav DVD in the unit in order for it to display and track your where abouts. Most GPS systems you load in the software and thats it, the software is stored in the system.

Nope, it requires the DVD be left in.

Thats what I thought. Why does a advance technology companies like BMW have products that cost $2000 that have less performance or advancements as other companies GPS systems that cost $400-1000.

Portable and aftermarket NAV systems often have limited internal memory (my Magellan has 128MB of flash memory to hold map data).

There is a Garmin GPS unit I've been looking at for flying that is a GPS unit and PDA that you can load the Americas Aviation Database in for flying, and it will accept the automotive ground database for driving but you do not have to keep a disc in the system. Everything is held in an internal memory. The basic system is $1100, with the Americas Aviatioin database, the auto kit with drive database is an extra $250. They also have the euro Avaition and driving database software available too. You just do not have the built in feature, but you do have one system that performs many functions. As an person in the aviation world I see it as an all in one use type avenue to persue, but the built in system would be a nice thing.
And I've never really need a nav system for driving before here in the states or in europe, asia, or where ever my travel take me. It would be just a neat feature for convenience.

Garmin has others much cheaper but the display isn't nearly as nice though.

I guess my overall point is that if you could just load software and then remove the disc, it would be a nice thing that if you did ED then the delivery center could load the Euro database for those spending time in europe, then once stateside reload the North American software. Then pull out the disc and have the DVD harware also perform other functions, say as a CD player. That way you have one less slot and head unit, at a cost savings. Since they do make player that run DVDs and CD this is a possibility. Just makes sense to me. IMO.

That is a lot of flash memory to put into the NAV computer.

You should try the nav in our new Trailblazer. The disc slot for the nav dvd is the same for the cd player, you can't navigate and play a cd at the same time! At least BMW uses a separate drive for the nav dvd. Thankfully we got xm radio too, so that kind of makes up for it a little bit. I couldn't believe that they would design a system that way. Another downside is that you can't enter address information while the car is moving like I can in the BMW. In short, the BMW nav isn't perfect, but it's better than the GM one in some cases.
