E 320 Phone

I have an integrate analog phone in my 2000 E320 that needs to be updated to Bluetooth by the end of the year. Does anyone know what kit I need? How much it will cost? thanks

If you have a motorola V60. The dealer has a bluetooth modual(400.-500)for that phone that just sits in the cradle. If you have a timeport, i think you are left high and dry...
