We recommend you to buy extension from your local authorized distributor. (Please refer to our dealer network http://g-scan.gitauto.com/eng/company/network.asp)
If it is not possible for some reasons, you can purchase directly from us via PayPal service
(Also, if you are using a G-scan1, and your SD Card is of an old 2GB capacity type, please be advised that you have to purchase the 4GB SD Card together with the subscription extension because the latest version software collectively exceeds 2GB SD Card’s capacity.)
If you want to extend software subscription via headquarter, please log in to your account and continue at [MY G-scan page].
** G-scan users whom reside in the U.S. should contact CAS of New England at 1-866-368-6657 or email@example.com **
