You cannot reformat an L-series, so your stuck with whatever it is loaded with. Stay with a late J-series or K-series.

> - How do I know which settings to configure later? Maybe I should first check all the settings on my SYNC 2 and then use the same later? I have a reverse camera (OEM) and a Sony 9-speaker ACM without DAB so I guess I will have to configure those.
> - The USB hub is confusing me; there are versions with 1 or 2 USBs. And Chinese are selling the Type-C one (I guess that’s not an OEM one?). Which one is better? Will my front USB (below AC) continue to work? I would definitely love to have two, one for AA and one for my 64 GB USB stick with music.
> - Do you have a recommendation for the GPS antenna that works the best? I see some people reporting problems with some antennas.

NAV is updated either thru Ford if the APIM is originally equipped in the vehicle (ESN licensing) or in this case thru reformat of the APIM.  
Sync 2 settings are mostly not applicable to Sync 3, a lot of folks make this mistake. The best way to start is to be on a community like this for help, and to find a vehicle similar to yours but equipped with Sync 3, like a later model year. Get the VIN of that vehicle and look up the asbuilt data at [Select Country - FordServiceInfo.Com](https://www.motorcraftservice.com/SetCountry?returnUrl=%2FHome%2FIndex). This will give you a close match and minimize the programming.  
Ford does make USB hubs with A and C connectors. Purchase your hub thru a Ford service dealer or reputable representative.
