#2992 of 3260 Denali Nav System, Lights by peterrollout Oct 03, 2005 (2:10 pm)
Just bought a 2003 with NAV. Was driving it back and started getting messages that DVD disk was not reading properly. It stated either disk could be damaged or dirty. I cleaned it repeatedly and got it to work but error message came up again. Thoughts? I also wanted to ask if anyone has put optional bulbs on theirs and what they recommended. Manual shows 9005s for both high and low.

Replying to: peterrollout (Oct 03, 2005 2:10 pm) I installed Sylvania Silverstar bulbs on my '02 Denali and have been very happy with them. It does have 9005 bulbs for both low & high beam. Still trying to find Silverstar bulbs for the foglights though.   Can't help you with your NAV problem - it wasn't available on the '02 models.

Replying to: kshadek (Sep 26, 2005 11:12 am) I recently bought a 2005 Yukon SLT replacing a 2001 SLT with the exact same 5300 Vortex engine and similiar equipment. My 2001 had considerably more power and acceleration; ran strong. The 2005 is a total dog...Very poor acceleration, feels underpowered, etc. I can't figure it out except that maybe GM has changed something in the computer (timing advance...) to tweak more gas mileage out of it. I loved my 2001, but am quite disappointed in this new one. Am taking it to the dealer this week.

Replying to: acefield (Oct 03, 2005 4:38 pm) Check the rear end (axle) gear ratio of the 05 & that of the 01. My guess is that you probably had 3.73 gears in the 01, and have something much lower numerically, like 3.42 or 3.21 in the 05. The lower numeric ratio should give you better fuel economy on the road, but has less accelleration & towing capacity. If the gear ratios are the same, then I would definately suspect some other problem, as I believe the 05, 5.3L engine is rated at more HP than that of the 01.   I currently have an 01 YXL w/ the 5.3L & 3.73 gears & have been satisfied with the performance. My 01 was rated at 14/16 MPG, & I bet your 05 is rated much higher. I even tow a 34' travel trailer, weighing in excess of 8000 lbs w/ no problems. I know I am pushing the limit, but I had the 01 YXL before we upgraded to the bigger trailer. Next time I'll probably go with a 3/4 ton & 4.11 gears for more towing capacity. Enjoy your new truck, & hopefully better fuel economy.   Good Luck, Dave Replies to this message: acefield (Oct 06, 2005 3:09 pm) beach15 (Oct 07, 2005 12:17 pm) arrie (Oct 08, 2005 8:05 am)

Replying to: cornellpinoy (Oct 03, 2005 4:00 pm) I assume you mean that the SS fog bulbs are hard to come by, as opposed to asking if such bulbs exist...in which case, you just gotta search a bit harder. Replies to this message: cornellpinoy (Oct 04, 2005 5:13 pm)

Replying to: tdoh (Oct 04, 2005 11:24 am) That is what I meant - haven't seen SS fog bulbs at any of the auto parts stores I shop at. Not really a big issue for me since I rarely use the fog lights.

#2999 of 3260 NAV system software ? by gipper2nd Oct 06, 2005 (10:23 am)
I own an '03 Denali with the Nav system. I would like to update the map C.D., but almost choked when the dealer said the cost was $375.00 for a new C.D. Anyone know where to get one other than the dealer? P.S. the one that came with the car was dated 2002. Replies to this message: tdoh (Oct 12, 2005 9:03 am)

Replying to: circutmann (Oct 04, 2005 9:14 am) Thanks a-lot. You are apparently correct. I don't recall the axle ratio in my "01, and I no longer have the papers. However, my "05 has a 3.42 gear ratio has you suggested, which is quite low. I bet this is a lot of the problem, but I still think something else is different perhaps in the timing or timing advance, because I still have a very unresponsive accelerator and it sputters and coughs at low speeds such as 1st and 2nd gear. Still awaiting the evaluation from the dealer. I greatly appreciate your input. Happy trailering!   Charles Replies to this message: beach15 (Oct 07, 2005 12:17 pm) arrie (Oct 08, 2005 8:05 am)
