Here's an update on what is turning out to be a pretty frustrating experience with my dead head unit. Last Monday, March 1st, I dropped my truck off at my local dealership (not the dealer I purchased from, but the one that I typically use for service) to have them diagnose my dead head unit.
I went in with every expectation that they would tell me that the head unit would need to be replaced, and that it would have to be ordered. My prediction was correct, and I was told that it would be 3 to 5 business days to get a replacement. Figuring that the turn-around would be quicker, and not wanting to drive the truck without being able to control the climate, I decided to leave the truck at the dealership to try to keep the issue top of mind for them, and to make it available for immediate installation once the part showed up.
Fast forward eight days to today, and the part arrived, but it turns out that the head unit is comprised of two modules, and apparently the failed one was the one that they didn't order. The service advisor said that they were trying to source the module from both Panasonic and Pioneer, which struck me as an odd thing to say. I have always thought that these were Denso parts, and wouldn't really expect for there to be multiple vendors making Land Cruiser navigation/climate/audio modules. Perhaps she doesn't know what she's talking about.
The long and short of it so far is that after a week of waiting, I have to wait more because the dealer's service department is only just now figuring out what exact parts they need to sort this problem out. I am finding their delay to get to this point to be highly annoying.
I know that the root problem is not the dealer's fault, but with the amount of time that has passed, with the truck in their possession the whole time, you would think that just about any replacement part on the planet could get to Southern California by now, COVID or not.
Hopefully my problem is resolved soon, and that they are able to dismantle and reassemble my dash without screwing it up. I definitely expected to be far more than 2000 miles down the road before having service people taking things apart.
Once I get it back, I'll take a pic of the door jamb to get the manufacture date, so any of you with build dates in the same range can start fretting about your head units crapping out too.
