I found this during a parts storage cleanup: a Kanatechs CAN-BUS adapter, GE-XA02. Version 4.0. This allows you to extract the signals needed for car navigation installation from the CAN-BUS, making connection easier. All included accessories are shown in the photos. The "general-purpose connection code" in the fourth photo is missing, but if you have a Kanack Planning installation kit compatible with this unit, a 4P connector is available, so the general-purpose connection code is not needed. Since it's 4P, you can connect it directly with electro-taps or similar. A copy of the instruction manual and Dip-sw setting table (for Ver 3.0, for reference only) are included, but please note that the print quality is not very good. There is some modification to the harness, but there are no issues with use. Please check the Kanatechs website for vehicle compatibility information. It's been several years since I removed it, so I will handle any issues with a cancellation. 251224
