Does anyone know if this is a good way of bypassing the Nav / DVD on the 940? Im just getting ready to install this in a 04 F-150 and want to make sure its a good way to go about it...... Please let me know.
Here is the link

it has me installing a new wire above the mute wire and and slicing it to the parking brake wire then grounding both of them. Is this good or just a waste of $10?
