Raymond N Priscilla,
The other nice feature, it mutes your music when you accept a phone call. One less manual function for the driver.
There are other units that actually do more, this one only has 4 audio channels out, no separate sub out.
What I would really like is one that has a digital audio input and does Dolby 7.1 surround sound for when I use it for the TV...maybe next years model.
