Hi Folks,

New to the forum just joined. Was looking for help with my nav system. Have a 08 Silverado 14,000 on it, bought from local dealer traded my 06 1500 Silverado which I loved. Love the new truck but this whole nav system thing has me bummed. Seems the nav disc was missing when we purchased the truck, have waited three weeks for them to turn up a disc. First one was a ver 3.0 and would even load said it wasn't a map dvd. The second one they got for me is a ver 4.0 GM pn:25974486U not sure where they got it seeing all my research says they are back ordered. The disk look like and OEM and came plastic wrapped and all. So here's the long story longer inserted this disk it said it was updating system and did a software load. System seems fine except the guidance system never prompt for turns or if you go off route. It does tell you to proceed to highlighted route and tells you it's suspending route guidance at the destination. I call the 800 number on the back of the disc gal check with tech but says if voice prompt is on should work must be a bad disc. Now I'll explain I've tried a disc I purchased off ebay as well PN:25912408U and it works excatly the same as the ver 4.0 disc. Any advice are they poorly done copies of an OEM product?? Are the nav disc copiable?

Disk pn:25974486 is the current disk..2009

Disk pn:25912408 is the previous disk..2008.

 

I have the 25974486 and it works great.

The loading software thing happened to me too when I put the 2009 disk in.

 

Go thru the settings and make sure you have the voice prompts turned on and the volume set at the proper level..ie..loud enough to hear.

 

You can adjust the VOICE volume separately from te radio volume.

Assuming you can get the voice prompts to come on at all...when it says something...turn the radio volume knob "UP" or "DOWN" as needed to have the proper volume for the voice prompts..but you probably have already figured that out.

 

Mine will tell me when I go off of the route it think I should be on. I am not sure if there is a setting for that or not.

There are setting to allow / disallow, toll roads and ferries.

      upgrading speakers on 2026 std cab WT...

      By bwiese · Posted

      I don't wanna do major surgery/upgrades, behind-the-dash work, add amps, change radio etc. on my '26 std cab WT. On the WT, it has the base 7" IOR infotainment setup, and only two speakers (doors). Since I listen to classical, looked around for speakers that do well and dug thru reviews. Two-way speakers were found to be better than 3-way. So I've ordered a pair of  Infinity Reference REF-9632IX 2 way speakers.  [These may  or may not have been discontinued / succeeded by the 3-way ...9633 ones.]    These speakers are lauded for 3 ohm and 94db sensitivity spec so they'll work well for ordinary base car radios without amps and offer better performance (quality,  strength) than  default base paper-cone speakers. They'll be installed in a few days and I'll let y'all know what I think. Bill W San Jose

      Thanks!   Changed out the rear shocks today to Bilstein 5100s.  So far feel much better. The stock Rancho were wore out.  Lots of heavy hauling (2 moves, home renovations, etc).  Next up is new BFG tires Monday.  Cant wait the current tires have little to no wet traction and are super loud (hum)

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      How about I just point to the factory pans stand pipe little drain plug and claim its a pan with a real drain plug !. I just couldn't swallow the fact that a Dorman pan which at this point is probably the only pan out there that fits the gas version truck cost that much up here in Canada so I decided initially anyway to skip it and see what I thought of pulling the pan method and down the road if I felt inclined enough then I would either install a drain plug kit in the factory pan if there is enough room for it, or have a bung welded onto it, or put an aftermarket pan on. The thing is if the pan is not pulled then the magnets in the pan can't be inspected and cleaned or if wanting to change out the filter. However of course it certainly would make the job easier to be able to drop the oil first before having to handle the pan if dropping the pan that go around was the goal.    I knew a guy locally that was doing custom field spraying years ago with a pickup pulling a ground driven sprayer, I believe it was a GM pickup with an automatic trans. He had a drain plug in his pan and would drop the oil out of it once a week and top it back up through the dipstick tube to keep refreshing a portion of the oil often and that made the transmission last far longer than had he done nothing. Soft fields pulling 500 gallons of water at the start of each mixed up sprayer tank batch and in low range sucking along. I imagine he got some tips from other custom sprayer outfits doing the same thing at the time and learning from their blown up tranny mistakes. Transmissions then had no lock up converter so would cook the crap out of the fluid slipping that much and it would not have been synthetic fluid either.
