For once, @Guy posted about a mod that I could do that did not cost me any money. This has to be a first I noted the time frame was up to 10 minutes to recognize the drive, initialize and begin the “upgrade” and the upgrade time was about 20 minutes. That’s right about the 30 minute mark and about the time I think the truck shuts off on “accessory” power to preserve the battery. At least I think it’s 30 minutes. I was too lazy to find out in the manual so I started the truck. it took 1.75 songs to see “updating” on the screen and just over 3 songs to complete the upgrade. as previously mentioned, Map do not work immediately after the upgrade. You need to power cycle. I have noticed in previous interactions with Lucille that she can be a bit stubborn about sync things, so I shut the truck down, got out, closed it and did some other stuff. I came back in a few minutes and fired up the accessory mode, maps were fine.
