Some basic questions reguarding the alpha

[Marlin]

I have never used the alpha, and have som basic questions for the alpha users out there.

I live in Norway, and will be using it there, can I use the same sd micro card from my astro, with the garmin topo maps?

Witch frequense does it use?

Can I use the same antennas (handheld, car) as on the astro?

Is there a separat charger for the handheld battery available( so I can charge a spare outside the handheld)?

How does the touchscreen work in low temperatures(as low as -5F/-20c)?

In advance Thanks
