When purchasing the unit, you are entitled to one year of free updates - PC and mobile versions. We reserve the right to charge an update fee after one year, which will entitle you to another year's updates - however, this has not been implemented! (We are too busy implementing more functionality in GS-911!)
Please note that your software (all Release versions) will not stop working after a year, and you are under NO obligation to purchase updates - it's your choice whether you want to or not...
Also, if you have not updated for a while, then these are not back-payable, i.e. there is no need to catch up on the payments for the years you've missed in order to get the latest update (as many diagnostic software manufacturers insist).
Our suggested cost for updates would be US$49 for Enthusiast versions and US$99 for Professional versions respectively. It is common in the software industry that yearly updates are charged at between 20% and 30% of the cost price of the software, but you will see our ranges would be between 14% and 16%.
HOWEVER, we have not implemented this, and only reserve the right to do so...
Up to this point, all updates have been FREE... since GS-911 was released in January 2007.
