If you connect it to the bmw plug....the canbus will power it down after a few minutes..... But there have been some reports of the canbus not doing so....and with the result of a dead battery. Mine turns off after a few minutes.....which switches the unit to battery power.....and at the end of the day I just switch it off with the installed waterproof switch. Had no issues.....
I like your setup. Can you tell me the p/n and the vendor for your switches.I have been looking for some weather proof switches.
Just a little heads up to all. Make sure you make your connections weather proof. Raychem makes what we refer to as environment splices. I am sure a quick internet search will reveal several vendors.
