2002 VOLVO V70XC Electrical System Problems

FIRST, I GOT A MESSAGE ON THE INSTRUMENT PANEL SAYING "SRS AIRBAG URGENT." A FEW DAYS LATER, THE PANEL STARTED TO INTERMITTENTLY WORK. WHEN IT DOESN'T WORK, I HAVE NO WORKING SPEEDOMETER, FUEL GAUGE, ODOMETER, BLINKERS (ALTHOUGH THEY STILL WORK OUTSIDE THE CAR), OR ANY OTHER LIGHT THAT WOULD NORMALLY BE SHOWN ON THE PANEL. OCCASIONALLY EVERYTHING COMES ON, THEN IT FREEZES, AND EVENTUALLY TURNS BACK OFF. TOOK IT TO SHOP AND THEY TRIED A DIFFERENT PANEL BUT IT HAS TO BE CODED IN AND THE SOFTWARE WAS NOT COMPATIBLE. TOOK IT TO ANOTHER SHOP AND THEY SAID THEY COULD TRY TO SEND IT TO SOMEONE IN CANADA WHO REBUILDS THEM AND RECODES THEM SO THEY CAN BE REINSTALLED, BUT THE MECHANIC SAID TO WAIT UNTIL HE HAS MORE INFORMATION. OBVIOUSLY, THIS IS DANGEROUS FOR ME TO HAVE TO GUESS WHAT SPEED I'M GOING AND TO NOT KNOW HOW MUCH...
