If your head unit doesn't support iTunes tagging! This is a must have product to be able to use the iTunes tagging feature of the KTC-HR300. It is a nice addon, but you can only use hd radio or bluetooth or sat radio. You can't expand with all three. It is nice product, the display does not like being cold the display fades out until it warms up in the car. Sonic price is great.
