sorry to dig up an old thread but i too have had these errors, "error 1", "error 3", etc, etc. (usually i just quickly press FM then CD again to sort it) but never until last night had the "alarm" message?!?!
does anyone know what this is?
The other messages dont really worry me but this one does as it comes with its own beeps lol!
Is the headunit in any way linked to the car alarm system? (not likely imo)
All the best
