What Cartridge is needed for a MT2500 Snap-On Scanner Tool? [2004 SRX]

Well my dad given me this scanner tool from snap on and i have no clue how this thing works.
He gave me some cartridge that came with the kit he has but nothing was for anything newer then a 1999. lol

I have a 2004 Cadillac SRX it has some DTC codes and would like to use this scanner to its optimal protential. what cartridge should i get? lol

that scan tool is worthless on newer cars … only thing you might be able to do is generic obd2

dont bother trying to buy a cartrige for it … just get a decent actron piece … one that explains dtc’s goes for about $200

Dam Snap-On! lol

OBD2 generic works fine if you know what ur doing
