I bought the JBD and CAN tool from Burger a couple of weeks ago and I've decided I would rather add a sub from Musicar NW than keep this upgrade. I've only used it less than two weeks so its essentially new. I didn't change any settings from default. This is like getting the CAN tool for free and since Burger is out of stock, it might be your last chance for a while. I'll ship immediately. Just lemme know.
