I am interested in an Acadia, and I am trying to make the price right. Would it be wiser to forego the NAV system and just use the Onstar NAV, and can you still get the auto climate controls without the NAV.

Thanks in advance

P.S.- I like this site much better than the other(so much so that I Joined)

You have to order the SLT 1 or SLT 2. From what I hear the onstar dirction system works pretty well. I haven't tried it myself yet. But you can save the directions and see them on your radio, or just listen to the audio. Its linked to GPS, so will says things like "turn left in 50 feet."

They are 2 different animals.

NAV ismoredetailed and you can scroll to other streets to see if there is another way around or check your surroundings.

Onstar is like someone reading you directions over a phone.

If you have the means I woluld do the NAV if you feel you willutilize it alot.

I've never had a nav system, but I'm very impressed with onstar's directions. The earlier post said, and they were correct, that the directions are spoken via computer through your radio and the directions are displayed on your radio. Arrows point you in the right direction and they also tell you how many feet you have before your turn. If you miss a turn, the directions will help you to correct for the error.

The other post said that if you travel a lot, you'd probably enjoy the nav system more, and they are probably right. The one downfall with onstar is that there have been a few cases where when the customer service rep tried to download the directions to my vehicle, the transmission was interrupted. I had to call back and either ask them to attempt the directions again or they would verbally walk you through requiring you to write them down which isn't convenient when driving. However the reps are extremely personable and it's a good experience overall.

I am still learning the Nav and am liking what it will do.
yesterday I programed my Dealer location in cause I had to go back after work. It's 44 miles away. It asked if I wanted the fastest, shortest, or scenic route. What ever I punched in it was showing using the back roads. I didnt have time to readjust it and took off.

While in route it was telling me to turn and I kept going straight. It then told me to turn around ahead at a legal u turn around. After a while it picked out the next shortcut and told me to turn again. I kept going and as I missed its suggested route it learned the next path to my destination until I arrived.

Pretty cool.

P.S. 44 miles-2 gal= 22mpg ;D

Nav question - how recent is the map data you get, and how often do they update it? Do you have any idea what the DVDs cost? I'm just curious because my neighborhood is brand new. The road I live on didn't exist 4 months ago. In fact, it's JUST now showing up on google maps. Just wondering how that would work w/ the Nav...

I'd be very surprised if the Acadia's system is that current. Typically, the manufacturers release (read: sell) updated disks about once a year. Even then, the maps usually lag 6 months to more than year. All the manufacturers buy their mapping data from a couple of mapping companies, and then format the data for their specific navi systems.

Navagation is something that you can use everyday for every trip (if just for the map and GPS feature). Whereas, it would get very old, very quick to call Onstar for turn-by-turn directions.

Basically, it is directions versus an actual map.
