Title: Pinout for GNS FM6 TMC receiver?

I have an active cradle from a GPS unit and the manufacturer denies it has any TMC functionality although it comes with this chip inside the cradle AND an FM antenna. Nevertheless, I could not get any signal to show up on the scope from this capsule and I probed all the pins.

I only need the TX pin, I can work out the stuff from there. Perhaps some pull-ups or pull-downs are deactivated causing the chip not to go live. The 3.3V supply is available.

From what I've been able to read on the forums some Navigon TMC receivers also use this module inside.

Any update on this? I haven't tried playing more with it but it's not giving out any signal so it might not be powered correctly.
