I have a 2016 Edge (so MY20 does not apply) loaded with 3.3.19052 and NA 2.20 (2020) maps. (I’m staying on 3.3.19052 so I don’t have to upgrade the USB hub. Yes, I’m cheap.)
I’m only looking to upgrade to 2.21 maps but this option doesn’t come up with the “Upgrade Maps Only” option. I do get the 2.21 option if I select a full 3.3.19052 install, which also switches the install mode to Reformat. I’m trying to ID why the 2021 maps require a reformat and reinstallation of the same Sync3 version, but so far haven’t found it. A little help? Thanks in advance.
If you don’t have issues with your hub on 3.3, you likely will not have problems on 3.4 Wherever you got that information it is wrong. The issue is that the hubs are not CarPlay compatible, but will still work for AA.
But why does the info above say old version is 3.0?
NA maps are ESN locked and there is no autoinstall option on locked maps. You need to reformat.
Old version, i.e. version installed when I purchased the vehicle, was 3.0.18xxx. Current version is 3.3.19052. I reformatted and upgraded to 3.3.19052 a year or two ago.
EDIT: I tried the lowest available version of 3.4 (3.4.19052?) and still had the car hub problem, unfortunately. I suspect that all 3.4.x versions expect the newer hub. In retrospect, I would have stayed on 3.0.x but didn’t know about the car hub problem when I first reformatted. Now going back to 3.0.x isn’t an option.
Yep, I know that the hub is not terribly expensive (more if I have someone else install it, but still not bad). I’ve just elected not to do it.
It’s not that I have “bad info” regarding 3.3 vs 3.4. It’s because I tried it (see Need help downgrading: 3.4.x to 3.0.x). I received the “USB hubs are not recognized” error when I first tried to upgrade to 3.4.x. I tried the lowest available 3.4 version and still received the error, so went down to 3.3.19052 - no more error. I’ll probably install the upgraded hub at some point but don’t want to right now.
Yes it’s only an error message, but one that I don’t want to have pop up every (or every 2nd or 3rd) time I start the vehicle. I’m not using CarPlay so the error message only matters from the perspective of annoyance. Again, I might change my mind down the road but at the moment I’ll keep it where it is. Thanks.
