BOTH keyless entry keys quit working at exactly the same time, so i dont think its an issue with the charge on the keys, and the right side of the Idrive screen quit working, i think its the GPS side of the screen, but i really cant remember what information is displayed over there, its lit up, just doesnt display the information that it normally has.

not sure if its related or not, but the "skip" button on the steering wheel for the radio also quit working at exactly the same time.

Does anyone have any idea's on what i should check first (ive already checked the fuses and all appear to be in good working order.

any help will be very appreciative, My wife is driving the car and is about to drive me insane with the lack of keyless entry......

BTW its a 2004 545i 6 speed manual with parking sensors if that makes a difference.
