Constant 12v for Raido

Hey where can I pick up a 12v constant for my Raidos Memory. My car is a 2013 E4

Thanks

The Unit need constant 12v to remember my Bluetooth connection via “Auto Pair”
If you guys are thinking about a Headunit for your Gem you should check out these Sony head units.

Is this it?

#10 on the fuse panel

On my 2013 the Constant 12v power was in the #6 spade
And keyed 12v power was on the #3 spade and then I just ran a ground to the chassis.
I can highly recommend the $180 Sony Bluetooth Headunit. It’s over 100watts and it rocks the 2 small 6inch speakers very well. It’s so easy to adjust volume and change tracks from your phone Ect.
