Phatnoise VA-012 PBOX with VW BEETLE Monsoon radio

[DOUGDANGER]

 I have had this phatnoise box in my 1999 a6 Audi. connected with the CD changer cable that came with the  car. worked perfect in the Audi which had a Panasonic CD changer. The question I have now is I have  VW 2003 beetle. With the monsoon radio. this car also has a CD changer but it is a kenwood. The plugs on both CD changers look the same and both plugs are round and have the same amount of pins.Both radios are CD changer capable. The phatnoise cable that came with phatbox. The CD end of cable plugs into both the Panasonic and the kenwood without any problem. Before I turn it on does anybody know if it will work or will it damage my radio.
thanks Doug

PS Also had it in a 1996VW Passat and worked fine.
