Geetech A20 don't know version

[JWKillTimeFPV]

Hi i've got the A20 its meant to be the GT2560 V4.1B board but i have doubts that it is. I bought it off Amazon UK.
When i go into the settings & gooto PRINTER INFO then BOARD it says
GT2560 V4.0
Baud: 250000
FW Ver: V2.0
HW Ver: V4.10
Protocol: 1.0

Can anyone please tell me if i have the V4.1B board & if i can run the BL-Touch on my printer & if so how do i set it up?
This would all be a great help to get sorted out.

Thanks for any help anyone can give.

if your printer came with the mount for the bltouch, it supports it. there should be 3+2 unoccupied pins on the breakout board on the back of the hotend assembly
can attatch pictures if needed
