Does it give sufficient warning before a turn? My wife has a portable Garmin that doesn't seem to give us sufficient warning of an upcoming turn. Often we are in the wrong lane.

You can set it to not allow major roads and it will take you on two lane roads. I like doing this even with places I've been to many time. Some of the routes it comes up with I never knew existed.

So does that mean when you enter a destination and it maps the route, the route itself is not highlighted in a different color or bolded to show the route as you drive it?

The nav in my '08 will highlight side streets, if they are on the route, and even if they are not on the route if I make a wrong turn. It will also recalculate quickly when I make that wrong turn. It does not say "Recalculating" as some units do -- it just does it.
When I once took a toll road, instead of the two-lane it wanted (I had it set for direct route) it wanted me to exit at every chance for about 75 miles, until I shut it off. But that error was mine. I should have chose the fastest route if I wanted to take the interstate.
It once took me right to a friend's house -- on a single lane road through the woods – and highlighted the route in red. His 2007 nav will not find his house -- closest it gets him is two blocks away. I suspect that some of the issues folks are reporting are being remedied with the newer updated systems, or in some cases the updated disks.

The parts of the route that are in areas that it is well aware of are highlighted just fine, just not all of the side streets. The highlighting would end where the side streets that were in "incomplete map data" areas began.
I had the version 3 disk. I think there may be a version 4 disk out now or something. I was originally under the impression that the version 3 North America disk was the latest but it was only one disk. I think the newest disks are a set of 2 so I am assuming there is a version 4.

There is an option to allow toll roads. If you haven't chosen that option It will keep trying to get you off if you get on one.

Yes, you can avoid major roads with a simple selection. If you really want to get fancy you can avoid any area you choose through a more complicated procedure. For example, if it just a specific intersection you want to avoid you can select it.
The voice warning starts 1/2 mile or 1/4 mile ahead depending on your speed. But you can have the distance to next turn displayed all the time. The other day it was showing me my next turn was 98 miles ahead. You can also have it show the next 3 turns with distances to each.

Navigation is worthless. I have lived on the same street for 7 years and when I get near my own street the nav unit says it will not continue to show guidance. When I pull into my driveway, it says I have arrived. The worst system have ever seen. My Garmin Nuvi is so intuitive and accurate that you do not need an instruction booklet. It also calls out the name of the street where you are to turn, the GM does not. On my next trip I will bring the Garmin with me and not use the GM unit as it does not recalculate the directions. Waste of money and I could have had a 6 disc changer instead of this expensive garbage. One learns from experiences and I have sure learned my lesson. GM is always behind the curve, however, so are the other automobile manufacturers when it comes to really hi tech. One day GM will learn that cheapest prices don't necessarily lead to best quality. A lesson they still haven't learned. Corporate profits seem more important, so if a manufacturer can sell them junk at cheap prices, there are there like a flash. There isn't even an I pod plug available if you order the nav. I should have known better. Sounds like I am mad about the nav. unit and you would be absolutely correct. It belongs in the garbage, not on my console. Now I feel better after shooting off my mouth, gets rid of the frustration and anger. Also good for the blood pressure.

I disagree - you can get the nav to recalculate your position and advise an alternate route. I don't know what you were doing, but I've never had that happen, even when I've been in Texas Hill Country.
As for the nav itself, a couple of things to remember. First, it is a generation behind the newest stuff. This nav was designed in 2002-2003 to be put into the 2005 C6 in mid-2004, so it doesn't work as well as the newest stuff. That said, it still works quite well.
The voice prompt will tell you major road names, streets, etc. Mine does it all the time ("Turn left onto 4th St.," "Bear right onto I-35 South," etc.). I don't know what others' are doing, but mine says it all the time.
The voice recognition, I have to agree, is next to worthless UNLESS you are sitting still with the engine off. Why? The microphone is in the A-Pillar, driver's side. Any wind noise on the glass, etc. cancels out your voice. Same problem with OnStar and the phone - the wind/road/engine noise cancels out the microphone a lot of the time. Don't bother.

To help you make up your mind about getting the nav, it would probably be a good idea to look at the NAV Manual (see below) and read about all the features that the unit offers. Hopefully, it will help you make a more informed decision.

But be sure to preview your route because this thing (NAV) is stuborn and it will not recalulate, once on going home from the Texas Hill Country it wanted me to do a "U" turn when I was less than 20 miles from home to do it, "its way". It tried for 75 miles, yes 75 miles, you think a woman is stubborn, this tops it. I finally turned the volume off on voice directions and finally cancelled it after 75 miles, I wanted to see if it would straightened out. This is a "GM jewel" this navigation. NAV = Cheap.

One thing I like about the system is that on long trips it recalculates your time to destination based on your speed made good. It does this after you have been driving for an hour and then makes fairly constant updates. My Garmin portable doesn't do this and my brother say his 2005 RL unit doesn't also.

My Garmin c330 constantly updates the time and mileage to destination. If I side track off the route it wants me to take, it readjusts the directions and also the time and mileage according to my new route.

My garmin also does this, but as I stated in my previous post, it just uses the wrong speed to calculate the time to destination. It uses the default speed for the road you are on. That was the only point I was making. Yours may be different since they make different models and may have different software.
