I have Mazda 6 MPS 2006year (Europe version) and I would like to install CARpc.
Car has original NAV with 7" motorized LCD.
What I want to do is change original LCD panel for Lilliput 7" touchscreen, I think it would be direct-fit.
Has anyone tried this?
Also, car has Bose audio system, but I want to add some aftermarket amp and additional subwoofer.
Which is the easiest way to add AUX input RCAs to stock Bose HU so I can hookup CarPc's stereo?
Where should I connect wires for preout so I can run it to aftermarket sub?
Some wiring diagrams would be great!

Thanks in advance.
