good morning my question is the following one because the dku nokia interface I can't program all kenwood radios and with the nokia ca42 if I can for your attention thank you The DKU-5 cable from nokia and the CA-42 for nokia phones, have the same type of chip, only vary in the version, according to the age of the cables, but the two program motorola, kenwood and icom. Of course, this apology, but the only DKU without a number does not know it and I could not tell you why you cannot use it.
