Well not today, but last night I updated the radio nav software to version 1200.

This fixed a problem with downloading nav directions to the vehicle using the MyGMC app and also added the Road Learning option to the nav unit and fixed DVD resumed playback on ignition cycle.

This update used the TIS2Web and the Tech2 in pass-thru mode but installed the software on a usb drive connected to the pc. You then plug the usb drive into the radio usb port and turn on the vehicle and it starts the update on the screen.

The usb drive can be used on other vehicles needing this update without using Tech2 or TIS2Web.

Update info is contained in GM service bulletin PI0816

Effected vehicles are 2012 - 2013 models built prior to September 24, 2012 with RPO UYS

Did this just update the software for the radio?

Pretty cool. Tell me more about what I could do with the MyGMC app on my ‘13 XL Denali.

Now if we can figure out a way to update the NAV data base like this instead of getting a DVD, that would be awesome!

I thought that was for sale? Why not switch off, 1 week for the Honda and 3 for the Tahoe? LOL

I know it costs more to operate but I love driving my truck everywhere and anywhere.
Agreed. That’s why I DD The Beast and I don’t care what it costs. YOLO as they say, no sense spending a bunch of your life in a vehicle you don’t love. Maybe get a canopy and battery tender for the Tahoe and drive it a couple times a week? My Silverado stays under cover.

Oh, I sold the 08 accord and bought a cpo 17 accord for daily duties, i like 35 mpg vs 17 mpg and the hoe was taking a beating and mileage was racking up with my 140 (there and back) commute.

I drive the tahoe on weekends and the wife dd’s the Denali.

I just don’t like that it’s sitting outside, she was a garage queen for 6 yrs.... and i like getting in/out of my car in the garage..... no heat, cold, rain or snow to deal with.....

Yes, only updated the Nav Radio software, not the map data.

The MyGMC app works in conjunction with OnStar. I can search or enter in an address and it will map it then I can choose to send it to the vehicle (basically not having to type in the destination on the Nav screen).

The app also has a keyfob page where you can start, stop, lock, unlock, and panic the vehicle from anywhere.

Has a locate option. Displays the vehicles current location on a map.

Also has a vehicle status screen. Queries vehicle and tells you mileage, how much fuel is in it, range, tire pressures, oil life percentage, and average fuel efficiency.

it's not to bad smell wise, I did a rookie move and took all bolts out and the cover just fell off and f&*(k like a dam broke and flooded the village

kitty litter cleanup on isle one!
Lol, only loosen the top and sides and remove the bottoms, then break the gasket seal (if rtv/sealant used) free at the bottom by prying a bit.

Now is a good time to replace the cover with one with a drain plug.

Never understood why they don’t put drain plugs on the rear like they do on the front. Of course in the front, I’ve seen people drain the oil out the drain plug only to find that the fill plug is seized up and won’t come out. Then there left with an empty differential and no way to easily refill it.
