For some reason, after years of not using uconnect (as it was regularly annoying to the extreme) I've decided to try it again and see if anything has improved. Plus attempt to see if I can do any firmware update and/or software updates it might benefit from.
failed at the first hurdle, cant even login to my uconnect account - since it looks like I originally used facebook to login, and the uconnect app claims that is disabled ? Ive tried just creating another account but run into the OP problem here - my car is associated to my facebook uconnect account.
call customer support - one ring then hangup.
I found a uconnect site with a chat function - got through to a real human it seems, who then told me this was a US support site and id have to go to the EU version - cant see a chat there - same phone number that hangs up, some mention of twitter support so Ive had to dig out my ages old twitter account details and change passwords to get into that just to try and contact fiat .
Funnily enough I had all these types of frustrating problems like 4 years ago when I last used the app, worrying that they have not tidied up their systems.
