I think it's basicaly software unlock and it's possible to find a new unlock for Mazda3 08 by inspecting audio head's firmware. Or even unlock DIS by editing firmware... Service centers probably have firmware for Mazda 3 audio head unit... Does anybody have it? Or does anybody know how to read and flash head's firmware?
Thanks for this tip! I just unlocked my trip computer on my 2007 Mazda 3i touring... others might be interested to know that I had to alter the steps slightly in order to get it to work. I tried it several times by holding the FM/AM and CD buttons while starting the engine, and nothing happened. When I held the FM/AM and CD buttons while turning the key to the "ON" position (without starting the engine), the "DIS ON" message popped up, and everything worked as expected.
I tried this trick on my car I have an 08 mazda3 I touring with a 6cd changer and steering wheel controls. When I told downj the am/fm button and the cd button its flashes DIS on but when I hit my :00 button nothing happenes....any help would be appreciated
I have a mazda 3 sedan 2006(europe) with cd player and i have changed it with a USA radio OEM Mazda 2008 mod(BOSE) because it has mp3 player.I have plugged it but it does not work the trip computer and i can not adjust hour.I push the buttons but nothing happens. I have tried to enable the trip computer it writes me DIS on but again nothing happens. Does anyone knows if i need to do
some rewiring?But the connectors fit exactly... Plz help

Thanks to _Kansei_ for the tip on activating the DIS and to enganear for the notes about changing the radio. For me, _Kansei's_ trick did not work (2008 iTouring, 2.0). I saw the DIS display light up as the instructions indicate, then I turned off the engine. However, when I restarted the car, nothing happens when I press ":00" (no INFO button on my car). I noted that the DIS lights up for only a few seconds then disappears, so maybe that toggles it back and forth from ON/OFF. So I thought maybe I wasn't turning the car off fast enough (e.g. while DIS is in the ON mode before the display goes blank again). That didn't make any difference.
My conclusion is that there must be certain cars in the production years that have this capability (like enganear mentioned about it maybe having some connection with the radio itself). I don't have a solution. I have a 6 CD changer already. Seems odd though, that I can SEE the DIS option, but after turning car off then back on again, nothing is different when I try to access the trip computer with either the "SET" button on the steering wheel OR the ":00" button on the radio itself.
I'm open for any suggestions, but I think I covered all the possible options...unless there is a trick I have not thought of?
