XM mk1

I would like to know if anyone has had prblems with alarm on an xm ????????

It keeps setting it`s self off for no reason !!
At first thought it was down to battery get US which I have now changed with a brand new one (Battery was duff anyway)

Still the alarm keeps going off after a bit sometimes 3-4 hrs later or just 5 mins after setting !!!

Just don`t know what it is, turned the in car sonics off still dose it !!!

Is there any ajustment on the alarm and were is it ?????

Is it just the same alarm on all XM`s as I could change it or will I need the IR key to go with it ????

I take it is under the wing as Xantia ones are ???

Any Help will be greatfull
