jensen 9512 redials last number from phon

I've installed many blue tooth enabled stereos and have had no problems linking them to my phone. UNTIL I gave my wife the Jensen 9512 for xmas. The radio works flawlessly until you activate blue tooth and it immediately dials your last dialed number three times before you can get it to shut off. It does this with each phone I link it to. Audiovox tech says the unit is bad..send it back. he doesnt know how much effort it took getting this thing in the dash. Any clues before I HAVE to send it back. Oh yea..while linked, any button I press on my phone triggers a redial from the radio.
