Hi i am using a MS90TS with latest updates. I want to install an older version of Mazda program actually it is install version. 7.70. On Mazda 2008 I cannot access Airbag module or GEM module (BCM). I tried different settings General, USA, Europe without no avail. I want to test out an older version of the Mazda Program is it possible to do if yes how do I do it?
