Antenna plug type in A pillar?

[deliriousga]

I saw a picture from Tool Pants in another thread where it looks like the antenna plugs in to the booster in the A pillar using a regular type antenna plug. Is that the case or is the plug in the A pillar the same "VW" type that's in the back of the Becker units?

I'm putting in a Garmin GTM 10 FM TMC Traffic Receiver to go with a GPS unit and it plugs into the antenna cable, but it only comes with a regular type plug and an GM type plug. If I can plug it in at the A pillar rather than order an adapter to go in the back of the radio it would be nice.

Thanks for the help!
