You dont have any pending OTA. GWM update was completed back in Jan but that was only 3.5.2 so you are due to get 3.5.3 and 3.5.4. Will look up FDRS for you tomorrow
You had an apim OTA attempt last month but it never ran to completion. Still shows in FDRS so it will likely retry OTA at some point or you could do your self
Get the mongoose. Then you always have the option to do your own updates as needed. Might also look into the vcx nano as I believe they may have one that is compatible with FDRS. The UCDS dongle will also work and give you a lot of programming capabilities.
If you have access to a VCM/Mongoose you can do yourself. OTA will probably come in incrementally. OTA does not show anything in progress although your GWM failed an update in Jan and does not show one in FDRS for that ecu. Might need to give that one a little push :)
