Radio Upgrade

I'm thinking about putting in a Garmin 250XL, but I'm having a little trouble finding the amperage requirement. Couldn't find it on Garmin's site, and my avionics tech didn't have the info on hand, anyone have any idea?
Thanks

The Comm and GPS power wires are tied together and go to a single 10A breaker.

I have attached the Installation manual to this post.

Thanks for the help. We found the info this evening before I went to work. Looks like about 5.5 amps when transmitting and 1.5 continuous.

Figure 1.3A of the attached install manual calls for a 10A breaker.

Thanks for posting that document. I also have a 250XL to install and need the instructions.
