I just got a Nav Unit 10377287 for my 04 Tahoe, Non-Lux. I installed the unit and when connected to a Tech 2 it can't establish a connection to the Nav Unit to de-activate the theftlock. Anybody have any ideas on what could be the problem?

My 04 Tahoe did not come with nav from the factory, and someone told me that in order for the tech 2 to be able to communicate with the nav unit I will have to use a vin number from a Tahoe that had nav from the factory. Does anybody know if this is true?

I can't help on why it's not communicationg but I don't believe the second part is true. I have an '04 NAV in my '03 Yukon and it works fine. The tech used my VIN to deactivate the Theftlock and everything took about 15 minutes. I'd maybe just check all the connections again to be sure they're good and maybe try a different shop (tech). I don remember it's not too east to find the right location in the system to get it done.

 

 

Good Luck

      OCI, not when but why?

      We did 250 on our tractors until we switched to Amsoil. We doubled after that.

      When I was there, most to all did not have an hour meter. They just did 5000 miles on regular vehicles and 3000 on police stuff. The modern oil change monitors should take into account engine hours, weather, etc. I don`t use the monitor on my stuff. I pull the stick, look at it, smell it, rub it between my fingers, etc. That`s my oci.   I have had many engines. Some bracket race. No problems doing things my way. I was in the mechanic business for 30 yrs or so. I still do things the old school way. Don`t care who laughs at me.   Understand, I was in the main shop. We didn`t do oil changes or tires. We had a service station for that. I don`t remember the hours they used for tractors, lawn mowers, etc. Something in my head says 250 hours.

      I don't know how far back vehicles had hour meters, be it driver accessible or diag accessible but was wondering if there was any rule of thumb your shop came up with in regards to an hour limit on engine oil regardless of the miles on the oil.    I know with construction or farm equipment its almost always based on engine hours for maintenance scheduling as no other metric really applies other than a seasonal time limit that one self imposes on items like engine oil.

      I'm not sure what to say on that mess but I will say that is an odd thing for that mechanic to speculate on as per assuming its been run out of oil a few times as the odds of that engine having instead piled up with a complete seizure would be very high if such events had actually taken place. However there is nothing saying that the oil has ever been changed although once again, what filter was on that engine as that would tell part of the story if its possible to figure out if its a factory installed filter or not. Too many items unknown and a lot of speculation, but regardless of that its one fubared mess that is mind boggling to see for a vehicle that new and its hard to imagine how it ever made it that far in life looking at the top of the engine.    His scanners, I've watched him before here and there and I'd have to say if I recall correctly that some of his scanning equipment is one or two steps up from a child's Exo Sketch 😋

      I agree. That`s a LOT of sludge for 12,000 miles. I tossed that out here since this is an OCI thread. There`s tons of people here that do not post.   I used to work on a city fleet. That includes police cars and fire trucks. Lesson is, not to only use the odo for oci. A police car has a ton of hours on the engine for the miles it shows. And, not just idling, directing traffic. They beat on these things.   Course, since it is a Kia, they were gonna use the "100,000 mile warranty" for their OCI.😉
