E46 Convertable: Seatbelt/Cruise/Radio/Brakelamp Issue

2004 330ci Vert with about 80k miles on it.

Go to start the car and the cruise control light will be on, and no matter if you turn it off or not, it won't matter it won't go away.

The top has become very finicky sometimes will go down sometimes it won't.

Passenger seatbelt light is flashing even if no one is in the seat

Now all of this doesn't always happen, its random, just a lot more consistent these days.

Ok 46 guru tell me whats going on?

1) Radio will work whenever it pleases, when it is not working its almost like it thinks the car is off, you hit the power button and nothing happens, yet the red security light is flashing like the car is parked and locked.

2) Brake lights are on at all times, no matter if the headlights are on or off, or if the brakes are being administered or not.

3) None of the steering wheel controls are working, no lights on the steering wheel. Flashers and wipers are working.

4) None of the buttons above ash tray are working, but they do light up.

5) The cruise control light on the cluster is on, when you turn the car on, but you can't set cruise or turn it off.

I know it is a lot to read however I feel like this is an issue that is going around with no answered solution. Searched to no avail.

Please PM me, or email me.

Any input is appreciated.

Pulled these two CEL codes:

P2806 Circuit Failure Data Exchange Timeout
P27A4 EWS 3.3 Interference DME EWS
