Yes you will have to run the soundgate. That is what they had to do in my car when car toys installed the changer!
However that soundgate is extremely sensitive, when they installed mine it put a slight alternator whine into my system and it has been getting worse ever since! So make sure after they install it, you crank the system, and let the engine run up through the gears while listening for a whine coming through your speakers. It is best do this with a really quite home made CD, or something you know starts off really soft, or you might blow a speaker.
Hookers need love too!
What we do in life echoes an eternity
