Review on Black Motorola HKKN4027A RM Series CPS Programming Cable - Enhanced for SEO by Patrick Arnautov

This cable is listed as correct for the Motorola RDU4100 on many third party websites. After I received the cable, it didn't work. Called Motorola and said the correct cable is RKN4155A and that this model is not even for sale. I tried to contact the seller well before the 30 day return period was up but never received a response. What a real PITA!
