Per la programmazione di questo apparato è necessario il Cavo Kenwood KPG-46 - COme per tutti gli apparati veicolari di questa epoca il collegamento al pc non avveniva direttamente alla porta seriale ma anche con l'utilizzo di chip di controllo (Max 232) - Se ne trovano in commercio già cablati e pronti per pochi euro, gli orginali costavano molto di più.
