#1593 of 3150 Navigation system sucks!
Aug 09, 2006 (10:56 am)
I can't speak for the eastern states, but here in the western states the Navigation system is totally useless. I plugged in Payson, AZ, to Telluride, CO, and got two paths. The quickest was totally wrong! 150 miles out of my way. Shortest was only 100 miles out of my way. So I put in a way point using what I knew was the shortest AND fastest way. Aha. That's better, I thought. Wrong! It had me turning into vacant areas where no road has ever been - and 20 miles from civilization. Into mountain sides. Etc. 80% of the time it was correct. Wonderful. The other 20% created sheer disaster. Should I trust it? No way! Which makes it worthless. So I consulted with another owner. She was trying to get from Payson, AZ, to Mesa, AZ. The Nav system tried to take her into a mountain! Again, no road was ever there.
OK. So maybe I needed an update (mine was 1.1). 2 hours of phone time later I got a real answer (this was NOT easy). Useless, but real. It seems in order to get the new upgraded DVD I need to join a subscription service. The problem is, the subscription service doesn't exist yet (August 9, 2007). The new DVD does, but it is not available without the subscription service - which doesn't exist yet! A $2,000 option which is basically useless. Hey, the car has been out for 8 months.
Ok, after three more calls to the dealership they are aware of the problem. They can't solve it, of course. I would suggest a massive letter writing campaign to Chevrolet - and maybe a magazine or two. GMC picked the wrong people for their Navigation System.
By the way, the currently available version 4.1 is for the Tahoe 2006, a whole different system. Yikes. How big a screw up is this!

Explain to me this HUGE waste. So you rotate all 5 and you don't have to replace them as soon. And then, what? - You have to buy 5 new tires instead of 4. More money, less often. Same difference.
I understand you feel you are carrying around a tire that you can't "use". But once it's used up, then you have to buy a replacement at your own expense.
I bet the savings you might realize by getting to "use up" the spare tire once ($100 maybe?) are offset by the extra cost it would be for a 5th matching higher quality tire and alloy wheel in the spare compartment.
Besides that, there's the tire pressure monitoring system. You'd either have to remount the tires on the same 4 wheels with the sensors (remounting would cost more for labor), or have a 5th sensor, which would again add to the purchase price of the vehicle.
I do think it would be nice to have a sensor on the spare, since I so rarely take it down to check on it. I'd like to know it'll be in good shape when I need it. But I have a portable air compressor in the car, so I can fill it up a little if needed. All else fails, call OnStar.
All this reminds me, I never reset the TPMS positions since the last time I had the tires rotated.

I disagree with your assessment, I've had a great experience w/our nav system getting us from Tampa, FL to Annapolis, MD and back. It also found shopping malls in Annapolis and restaurants as well. Compared to the nav system on our VW Passat, the Tahoe's is vastly superior. For instance:
Tahoe has touch screen, Passat doesn't (you don't know how nice it is until you've had to use a knob to spell out street names).
I searched for an Office Depot that I knew to be 2 miles up the road. The Tahoe's system found it, the Passat's didn't and wanted to send me to West Palm, about 4 hours away.
Nicer graphics on the screen (subjective, I know).
Granted I'm in the south east so we have different experiences and it is frustrating. I haven't experienced any other automaker's nav system personally, but I'll take the Tahoe's system any day and be perfectly happy.

Tires have a shelf life, and just like anything else they need to be replaced. By the time those 4 running tires wear out that full sized spare should also probably be replaced.
Rotating in 5 tires will make the whole set last longer. You can get safe running use from the "spare" if it were a matching 5th wheel and tire. With the "spare" being a running tire, and the set running longer, because of a 5 wheel rotate there is no waste, all tires will be used and worn when its time to replace them. Now when replacing tires the spare is usually brand new, with no miles, but still needs replacement because of its age. (A HUGE waste) This is a full size truck, and the spare is not a donut, there is no need to think that way.
Since we are in explaining moods, explain how the vehicles ABS, stabilitrak, 4 wheel Drive and rear locker systems will perform with a different make and different tread pattern. Its NOT a good idea, and for the cost of having a 5 running wheel its worth it.
As for the tire PMS any computer can keep track of 5 tires and where they are mounted on the vehicle that shouldn't be a problem.
As for the OE garbage Bridgestone Dueler H/T's the sooner those are replaced the better. For the cost of one more tire there is no reason to leave that garbage Goodyear Wrangler ST as the spare, which would hardly work backing up four premium tires.

I usually do my own tire rotations and I've found it an easier chore just to do a 4 tire rotation and keep the tires on the same side of the vehicle. This seems to have worked pretty well on my minivan where front tires seem to wear quite a bit faster than the rears. Plus both my cars have non-matching spares (I don't think I can put my studded spare into rotation and keep the cops happy in the summer).
I've seen various comments on the Tires, tires, tires about when a tire becomes stale. Six to ten year replacement interval recommendations seems to be the range.

Just curious. You say the EPA figures are not absolute and that you have had vehicles that do better and some that do worse. How then can you use them as relative values? Relative to what?

I can see that my FYI at least generated some comments. I do not want to beat a dead horse on this subject but I will at least respond as to why I CARE and why I hope others care.
Yes, I would have liked to have mounted the full size spare on the alloy wheel and patch the flat and put it on the steel wheel to use as a spare until such time as I FELT like buying a replacement instead of being forced to buy a new tire now. Therefore, I was forced to spend $200. instead of $20. It is not so much the cost as it is the newest letdown in my desire to support GM and the USA by buying one of their vehicles.
Furthermore, I have been someone who rotated 5 like tires in the past and I always managed to milk an extra 20-40K miles out of my tires. I guess I was spoiled over the last 12 years by owning Toyota 4Runners and Toyota Tundras that had full size spares that were the same tires as the 4 tires mounted. This was the case on all 4 trucks.
As I touched on above, I also care because I finally decided to break away from 12 years of Toyota Truck dependability to go for what was suppose to be one of the new bright offerings from GM with their new 07 GMT900s.
I went with GM because I have had 6 years of very satisfied ownership with a corvette and felt I could help in a small way by buying one these new SUVS to help keep GM going. Yeah !!
Finally, as you may see from this lengthy post, I do care and I hope more people begin to care or the US auto industry will continue to slide downhill and the Japanese, Koreans etc will continue to take more of our money to the other side of the pacific ocean because people like me get ticked off about a spare tire or something else that causes an inconvenience to me that helps me make the decision to return to buying a Japanese or German vehicle.
I CARE ! Go USA !!

The average American man is 5'10" tall while the average American woman is 5'5".
Some women are taller than some men. Relatively speaking, however, American men are taller than American women.
