Hello,
I have Toyota Matrix 2006, i have Mazda 3 2006 with VW Phatnoise where VW firmware was replaced with Mazda and bought MAzda cable and everything works fine, but i am curious, is it possible to replace VW Firmware with Toyota to be able to use it on MAtrix? if so, than where would i be able to purchase a cable? is it the same cable that CD changer uses? I have build in 6 CD changer, will i have to disconnect it to use VW Phatnoise if it works? thanks
