This I'm sure has been discussed before but I can't figure it out. I have read you can remove or at least unplug the internal battery in the SM10 and this will allow the unit to automatically power up when you turn on the ignition and shut off when you do.
Problem is mine is mounted in the funk on the correct cradle and for the life of me I can't get it off. So two questions. 1 Does removing the battery work and 2 how do I get it off the cradle to get to it.
