I had to look at it more than once and took a few minutes to find out from Bosch that I was spelling it correctly (B is not = R).
Something is wrong here anyway, because there is no GSB 18 V-110 C. Only the GSR 18 V-110 C exists. There is only the GSR 18 V-110 C, which in turn has the Bluetooth module. I hope this helps you.
