I'm not sure I understand your question.Like, I just want to have it work right. Dealership is helpless and told me to power it separately (even tho they installed) and I can surely dig into it and figure it out but I feel like something is wrong since it was “plug and play”. Help!
If the RF kit is installed correctly, it will turn off when you turn the ignition off, but the head unit will remain on.
Your dealer gave you the correct answer. If you want the RF to stay on all the time, you would have to power it separately. However this is not advisable, since as far as I know it doesn't have a remote turn on lead, and therefore would be on 24/7 and drain your battery.
EDIT: maybe not. See below.
