I tried to update on Friday but it still said 2964, so I spoke with VOXX a couple of times yesterday. The update did push (at least by Monday PM it had,) and you know you have it when it reads 2973. Same Fire OS 7.2.9.1 (PS7291/2973). The VOXX tech that I talked to said the two main issues they were seeing were the units staying on when you shut the vehicle off, (which draws on your battery and will eventually prevent you from starting your vehicle,) or the unit not coming on at all when you turn the vehicle on. Something about Amazon making changes on a baseline of code that VOXX made their unit off of, and VOXX had to go back and fix these issues. The best way that I have found when you experience either of these issues (I have experienced both of them,) is to take the negative cable off your battery and let your vehicle sit without power for a good 15 to 20 minutes minimum. (Make sure your key fob is away from your vehicle and all of the power is otherwise off everything on your vehicle before you remove the negative cable on your battery.)
Why I can get my one unit on the Right to take the update but not my unit on the Left, I don't know. I tried three times reverting back to factory settings, where you are prompted to select which language you want and so on, to no avail. It says it's downloading an update, then says installing, then when it looks like it's done, it still says 2964. I restart the unit and the same story - 2964. My dealer has a whole new unit to swap out on the Left anyways because the screen was marred from before we received it, but I'm a little concerned why I can't get the current Left unit to update to 2973.
