Does anyone, have an idea of what the parasitic drain of a Garmin GMR 18 HD radar is when the head unit is secured (off).

I imagine it is in the mA, but you never know. I was surprised at how much a NEMA 2K network drew when the head units were secured.

The reason for the question: I don't have an extra on/off switch to wire to, but can wire it to a battery distribution panel that can be shut off. (But this is cumbersome, not the long term plan, and also turns off a few bilge pumps.)
