I cannot understand that going for aftermarket HU with correct Fakra can interfere with this wires.
And worst part is that no radio signals! (though proper aerial connector is used for the aftermarket HU.)
That would be the correct way to do it though. The wire you want to tap is not meant for powering audio systems, we are just using it due to the limitations of the vehicle. I would highly suggest running a new, larger wire for your remote. It won't take you very long.
Most people don't change the headunit in the car as there isn't much need to.
