Origin B2 GPS antenna question

[Mr E]

Hello gang.

Have one B2. Have 2 cars now. Need second car kit. Origin want a lot of money for one.

So, I need the cradle, that's given.
I need either a ciggy lighter adaptor or to do a wee bit of soldering. No worries.
I need a GPS antenna.

Question. Origin want £30 for a GPS antenna. Ebay want about 4-10 quid. Anyone know the connector the Origin uses so I can get a cheaper one that works?

Not that I'm a cheapskate......

1) Didn't exist 3 years ago when I bought the B2.
2) Not as flexible fitment wise.
