Bluetooth pairing does not ask for PIN / can I force a pairing mode?

Hi!

I'm trying to connect my cars audiosystem to my arch laptop.
If I use the GUI in gnomes conrol-center, the car displays a pin to use, but I don't get asked to enter it anywhere.
On using the commandline tools, I also don't get asked to enter the pin there either:

$ bluetoothctl
[NEW] Controller 70:F3:95:33:34:53 nn-laptop-arch [default]
[NEW] Device 90:03:B7:B8:15:C1 Ford Audio
[bluetooth]# power on
Changing power on succeeded
[bluetooth]# agent on
Agent registered
[bluetooth]# default-agent
Default agent request successful
[bluetooth]# scan on
Discovery started
[CHG] Controller 70:F3:95:33:34:53 Discovering: yes
[CHG] Device 90:03:B7:B8:15:C1 RSSI: -50
[bluetooth]# info 90:03:B7:B8:15:C1 
Device 90:03:B7:B8:15:C1
	Name: Ford Audio
	Alias: Ford Audio
	Class: 0x340408
	Icon: audio-card
	Paired: no
	Trusted: no
	Blocked: no
	Connected: no
	LegacyPairing: yes
	RSSI: -50
[bluetooth]# pair 90:03:B7:B8:15:C1 
Attempting to pair with 90:03:B7:B8:15:C1  //car shows a pin here
Failed to pair: org.bluez.Error.AuthenticationRejected
[bluetooth]# 

I haven't found any way to convince these two devices to connect to each other. Is there a way to change the pairing mode or force a pairing?

Changing the sspmode:

sudo hciconfig hci0 sspmode 0

also has no effect.
