Terms and Conditions
Refund Policy
Due to the nature of the upgrade mechanism, any module which has been upgraded to the G-Lock standard must be returned to the CARVEC Systems UK office to be reset to the normal radian standard before any refund can be made.

Also note that a Radian can only be upgraded once. If a refund is issued and a module reset, it cannot be upgraded to the G-Lock standard again.

CARVEC System does not accept any responsibility for warranty issues with the original Radian hardware. The G-Lock upgrade is a software-only change to the module.
