The Hummer I am looking at has the Nav system in it and I was wondering if it is single disc or multi and if it plays MP3s

and can you play a music CD when using the navigation system?

Thanks

No mp3.......and no cd when using nav.......if it is factory system.

 

No MP3 is one thing. No CD when using the NAV is plain old stupid and almost enough for me not to get the NAV

go aftermarket on nav systems. they are cheaper and better. there are a lot of nav posts in this forum, check them out. a lot of good info.

 

That's not correct. No mp3, but you can listen to CD's while you use the NAV system. The NAV system has a Nav DVD, that is inserted behind the face of the unit. The cd potion of the player is not used for the nav., and is functional when the nav is in use. I have the factory NAV/radio.


Also, to answer another part of the question, the cd is a single cd player.

 

Wow, the dealer told me this info and that is why i did not get a factory unit. Do you like the factory system?

 

I remember our salesperson saying that the H2's were like that. I don't know if they still are, or will be .. just something that was mentioned when we were going over ours. Yes, I like the factory NAV system. Not only does it have the factory fit and finish, but it works great. When we were on a trip to the coast, we used it to find the Texas State Auqarium, and it took us right to the parking lot. I also like the touch screen, for the NAV and the radio. Normally we probably wouldn't have gotten the NAV and some of the other options we did, but we got the price down to what I would have expected to pay without them, so we got it.
