Any T680 Owners? Would love some feedback.

I am sorry, no answer here too, just question. Could you enable gps and phone yourself or you had to take to the dealership? Or anyone can live with this blocked features?
I am happy to hear some good news, because my truck is still throwing codes, after an software update. All DEF related and come and go. Especially when my DEF tank getting low. Low? At 1/8 tank it is derated my engine. I could fill only 14 gallons into the 21 gallon tank. But after every code gone. Tho I am happy with the fuel economy which is 8.2 in the first 5000mls. (The computer cheating rate is 2%) The DEF mpg is 212. 2013 ISX 450hp, 1550/1750, I run 1150rpm at 62mph.
The truck itself has some quality problems. The the dash accent on the left side of the steering wheel is bent and loose. The panel what holds the curtain simple come of the wall if you pull it a little bit. The most annoying, the head compartment knocking, rubbing on the roof when chases is moving. The first time when I used the differential lock, the light did not go out. I was afraid to start, so I played about a half an hour, when finally went off. Two days ago the gauges lights did not go on, so when the dark arrived, I had to stop, turn off the engine, wait a few minutes, to start again. Fortunately it works since.
I like the easy access to the fridge from the driver seat, but kinda awkward and small, but it is fine for me, since I go only for a couple of days at a time. I opted out the table because I do not need it and it looked like a pain, since it can not be folded and always occupy some room. Over your bed, or in the middle. You always have to deal with.

 

Oram I had the same issue with dash lights ! Mechanic showed me the cause and fix was to pull the fuse on the top portion of fuse block and reinstall ! to tell how you would do this I would I have to show you ! the mechanic said that KW is aware of issue and working on a perm fix ! as far as any new issues with emissions their has been none ! the DEF tank is misleading with its said usable gals I think the tank in size is 21 but with the possible baffels inside cuts it to 15 gals usable

 

Thank you for the comforting information.

 

Oram I am sorry that I miss your ? about GPS and Phone! on the GPS I beleave you have to call Garman and as far as phone if you purchased the phone package which is about $800 then the only service you will have is via sprint cell their sub company is bluefish it is all in your NAVPLUS handbook

 

Probably the dealership can free up the blocked features, but does not really matter. This NAVPLUS is pretty much useless. I made a mistake to have it. I have no idea how Paccar can put a so outdated electronics into an so called upscale truck. Seriously. This thing is a joke. But the truck is getting better. In the last 5000miles I have had only one check engine light, (what is gone after three start), no new problem, the fuel mileage getting better. 8-9, depend on the load. Even 9.4 on very light one. Tho, the dealership released the truck with unbalanced wheels.

 

Penske170...any updates on the truck/?

 

TULY007 ! 2 weeks ago the famous code spn1569 showed up again truck went to cummins spent 2 1/2 days in shop according to shop foreman they change routing of waterlines some more program changes and cleaned the def nozzle said was getting crsytals where it should not have for right now truck is doing okay mpg is 7.4 to 8.7 depending on weight and weather

 

Penske you're getting great mileage. What trailer are you pulling? We have curtain vans and may be getting some T680's. think we could get about 6.5+mpg? We're thinking 525 ISX, 13 speed, 3.55 rearends

 

Here at Prime, I know of two guys with the T680 and PACCAR MX engine getting 9.0 + MPG. We usually pull 78k loads cross country. I thought I was doing good with my Cascadia at 8.4, but these guys are making me jealous.

As far as the DPF and SCR systems, either you get a good one, or a bad one. You should find out within the first 50k miles.......

 

I am where you were in January. Ordered my T680 in June and was told it should arrive any day now.
ISX 500, 13 speed Ultrashift Plus, Super Singles, 355 rears,Diamond VIT, best radio, heated and cooled seats etc. loaded right up. Can hardly wait to get rolling. After possession an APU, auto greaser, FASS system and centramatics auto wheel balancers. Hope I have ordered the right truck. Now that you have had it for about 5 months, is there anything I should be aware or concerned about.
