What is the difference between the online version & AU version & US version

AUTEL divides the products they sell into online and offline models to differentiate distributors
Maxisys (MS) offline model Maxicom (MK) online model
respectively maxisys908=maxicom908 (the same function)
                    Maxisys908p=maxicom908p (the same function)

But models above maxisys ms909 (including ms919 ms ultra) (launched in 2021) do not have the same grade of mk series
So autel divides them (ms909 ms919 ms ultra) into online version and offline version, let's explain the difference between them

online version
Advantages: No ip area restrictions, suitable for customers who need to go to each country for services
Disadvantages: Compared with the offline version, there is no adas software (it cannot be used after purchasing the ADAS upgrade card), there is no FCA Gateway access (AUTO AUTH)

US version
Cons: Only available in North America
Advantages: Support ADAS (need to purchase ADAS upgrade card) FCA Gateway access (need to purchase an account to use) can get technical support and warranty from autel usa

Australian version
Cons: Can only be used in Australia and surrounding countries
Advantages: Support ADAS (need to purchase ADAS upgrade card) AU car (such as AU ford and Holden)
