I ordered the Audiovox unit online from Circuit City, all the stores in Austin are out of stock, but have the RCA kit. Online the RCA kit is out of stock, but receiver is in stock. Go figure.
I want the RCA kit for direct connection to the empeg, I can't use the FM modulator since my FM output on my tuner is kapoot... (no sound)
I think the unit is a bit bulky, placement in the vehicle will be interesting... I'll report as soon as I get it installed.
