Mate I'm not a Drewtech dealer
If you ask Drewtech they will tell you to buy a subscription
Because they cannot advise you to use the softwares that you find in other plce.
We have to understand this
All I will tell you know and for the last is that if you want to use GDS2 and Tech2win for diagnosis with a Mangoose Pro2 you can use it with softwares that you can find in the forum ( Use Search button to find out item )
For Holden and other GM cars for Australian market I think you can get softwares for Tech2Win too
But for GDS2 I really don't know ( I wasn't intreasted in this )
To release the GDS2 and Tech2win you need also to install the GlobalTis v32 ( which is cover SPS Programming too but for Opel cars in Europe )
If you want to do only Programming with the Mangoose Pro you need to buy the subscription
Now in the end. The GM Mangoose Pro2 is an approved tool by the GM.
It can works with tech2Win and GDS2 and can do SPS Programming in all GM cars
Tech2Win and GDS2 that you find in this forum are offcial stuff
But offcourse without subscription
I hope you understand.
Good luck
