So this is going to be a somewhat long convoluted update but bears repeating in case someone else runs into this.
This whole scenario started almost a year ago now when my Navigation suddenly stopped working, well almost. It would let me route back home but nowhere else, simply stated "We've encountered an error". So it was working, sort of. Of coincidence the exact same day my SiriusXM Guardian subscription expired. Naturally I called SiriusXM Guardian but they claimed that does not affect the navigation but to call Uconnect. Called Uconnect and they could not find any reason and told me to take it to the dealer. Calls went back and forth until Uconnect finally told me I needed updated software flashed. Called the local dealer and stated $200 gets it done.
Fast forward a month ago when I revisited this issue, just been too busy to pursue it. Started by calling Uconnect and asking about the OTA not functioning and that's where they stated again I'm behind in software versions which is the reason my NAV isn't working, stated I needed to flash the latest versions. I called BS on that but as an IT professional I also know anything is possible when older versions age out. Called the dealer and grudgingly made the appointment. Now we are up to date and still waiting for the dealers general manager to call, probably won't unless I initiate it again.
I've been fuming about this since yesterday morning so decided to call Uconnect again with some questions. I asked specifically what initiates the OTA updates? Couldn't answer. I asked if it's possible to do a USB flash on the 2020+ models, would not give a yes or no, take it to the dealer is all i got. I asked why their website states my truck software is up to date, she stated that's because it is. Wait one minute, you just stated i was behind in software versions make up your mind. Now she's getting testy and stated maybe your truck needs diagnostics to which I stated now you want me to spend more money? Said no thanks and hung up.
Started browsing the Uconnect site and found something interesting that made me stop and think suddenly while reading the FAQs;
"
Can my vehicle receive over-the-air software updates?
If your vehicle is equipped with built-in Uconnect® Access( Disclosure51) or
SiriusXM Guardian™( Disclosure25) connected services, you may receive over-the-air software updates. Vehicles with Uconnect Access have a 9-1-1 button( Disclosure52) and an Assist button located on or near the rearview mirror; vehicles with SiriusXM Guardian have an SOS button( Disclosure7) and an Assist button located on or near the rearview mirror. Vehicles must be located in the US and in range of a useable cellular network.", Checked the year and models of approved vehicles and mine is there.
Suddenly I stopped, remembering the whole thing started when my SiriusXM Guardian subscription expired. That got me thinking if OTA is connected to that then re-enabling should correct it and all things being good I should get OTA. Ok called SiriusXM Guardian and got a promo 6 month all included for $60, worth it to me to see what happens. Verified the services were re-enabled by starting truck and unlocking from phone. Go in truck and guess what?
The NAV now works exactly as it did before! So it is total BS that the NAV is not dependent on SiriusXM Guardian, remember I had specifically asked them what they did and they denied the entire thing. Well that's BS because after searching I did find some enhanced navigation packages, so they are connected somehow. Now I'm contemplating pushing this issue further, well see where it goes.
