This set is all that you need. Only a current thief or matching fuse adapter for ignition positive is needed. The cable for continuous powersupply itself must be plugged. The antenna works fine. Those who know a bit needs CA10 min for installation including the cable to ignition plus. I opted for the backup adapter variant. The cost 3.99 plus postage. In this version, you have to pull out only a fuse with ignition positive (eg, washer) and insert the adapter. The adapter then offers two slots for fuses. One for the washer and the other to the radio hedge again. The cables from the adapter must then only be extended and connected to the radio or the connector from the radio.
