When the light is red it means there is a problem with the phone, when it is green it means you are using it to call uconnect, roadside assistance etc. When it is out it just means that you are not actively using it.
As far as the radio I have it is a 2014, from a Jeep Grand Cherokee, I bought off a crook on Ebay, he lied to me and said it was from a truck, it works just fine and uses all the Ram logos and screens. What ticked me off was Ebay sided with him, and his listing stated clear as day it was from a truck, he even packaged it with the Ram bezel. When I got it
i ran the vin and found out it was from a jeep, the part number on back also shows up as a jeep part.
As far as serious goes, this is wierd I originally had the RA1 and upgraded to the RA2, when I did that I had to call them and pay a 15.00 fee to transfer it. When I installed this one it just worked, but obviously on a different account since the radio ID is different. When I look in the menu it says not subscribed? Not going to call them unless it stops working, may still be on the donor vehicle free trial?
FYI the shark fin from jeepguy's truck is different than the one I bought, mine looks like the one in the Tech authority website, not sure why only that mine mounts in the front Reg cab and his mounted in the back of the cab.
As far as connecting and registering with uconnect that might be tough as they mayrefuse us because our radios did not and according to them and Ram cannot be in our trucks. I am going to try though.
