Alright mate,
to the forum ...
In regards to your questions:
1) The dongle in the centre console sounds like the Bluetooth dongle.. There is a manual on the forum somewhere which will explain exactly how to use it (sorry I can't find the link at the moment)
2) I can't really help you with this one .. but I'm sure someone else can/will..
3) I pretty sure that all Zeds have Xenon headlights ... However the Facelift Zeds (Post 06) come with Bi-Xenon headlights ...
