Garmin Nüvi External Antenna

Hey Folks,

I know this is a long shot, but has anyone tried hooking up the Nuvi 350/360 external antenna connector to the stock shark fin Sirius Antenna? Would it perhaps work?

Are there any engineers or DIY tech savvy people here who might know?

Hmmmmm.......You would need the sat/nav antenna instead I think.
