What do you want doing with a Gs-911? You can probably get someone of ebay or elsewhere to connect / help you.. For less money.
I am on ebay to do just that. (and not too far away)
Motoscan is a cheaper option. A Bluetooth obd dongle, converter cable to the round bmw plug and the app itself with Ultimate option. You can use the dongle on your car as well.
I have both and tbh I prefer the GS911. I still have an old yellow one, not a new WiFi red one.
