Hello!
I had my Mazda 3 2007 (1.6 diesel) model for 6 months now and I recently tried to enable the trip computer as the car didn't had it available when I got it.
My problem is that the aftermarket navigation unit it has (QL-MZD501) is missing the buttons required to activate the trip computer. After some google-ing I discovered this website: china-car-electronics.ecrater.com, where is mentioned that the gadget comes "without CAN-BUS technology".
This means I can't get the trip computer enabled while having this unit?
Thank you,
Adrian.
