I didn’t know myself what an access profile is, for those too wondering - List of Bluetooth profiles - Wikipedia
You’d need to try and report back, or somebody with /e/ and a car able to use the function can test?
(as bluetooth needs to interface with the SIM, it reminds me of the ticket where Wifi needs to use the SIM for authentification. Then a system library needs to be built with /e/ to actually use that function - Wifi secured by EAP SIM not functioning - #2 by tcecyk)
