This function works on all 1615, 1616, 1815-xx, 1816-xx filters!
Mounting of the filter "in wires" ( The wires bundle going from radio to the car)
Connection secuence :
1. Take out the radio. How to take out - search for video descriptions on the sites www.ebay.com (the filters lots description), www.youtube.com keywords "mercedes tv free".
2. Find out the wires on the radio connector:
. GND: The brown thick
+12v: The red thick
CAN HI: Brown with red band (W164, W204) or Yellow with White band (W221)
CAN LO: Brown thin (W164, W204) Yellow thin (W221)
2. Cut off using the sharp tool the wires pair of bus CAN near the radio connector (10cm from connector).
3. Important: The first connection - always and everywhere - the GROUND (BROWN THICK) WIRE!
Because of a static electricity can fail both car units, and the filter too.
4. Solder CAN wires to a filter board, observing polarity.
Better to solder the points in the rings on picture of filter, because autodetect sometimes can't work good, as example when the radio is not from this car.
Remember - the wire with band is CAN HI (CAN+) !
5. Being careful, to smooth out a section of a supply red thick wire, and solder to it the power wire from filter.
Be careful - this red wire is powered upalways! Shorting it on the ground causes the fuse combustion in the car.
By default, for the navigation correctly functioning during driving, the function TV-free is always turned OFF.
For activation of TV-Free you need to press and hold more than 2sec the button "HangDown" placed on the right side of the steering wheel. Function will be active up to car sleeping moment or function may be deactivated by repeated pushing the button more than 2 seconds.
Here is description of possible troubles with filter 1815-12, 1815-13.
Attention! Concerns connections to B-CAN (A-B-M-class, G-class W46x, GL-class W164, X164)!
If after (fully correct!!!) Filter Installing into EZS ML W164 or GL X164, car will works unstable ( chaotic lights flashing, impossiblity to connect with EZS via Diags tool, the big count of CAN errors in control units), you need first make checking some control unitsin the Luggage compartment of the car and under the passenger seat - maybe some control units works in Emergency SingleWire CAN mode because they can be wet or damaged by water. Examples - the rear door control module is wet often, rear SAM too.
If one of car control units have some bus faulty by Body CAN (emergency SingleWire CAN mode working), then after installing of filter without SingeWire working future, the Body CAN bus can be work very unstable - Filter presence aggravates malfunction in the car CAN bus. For it's preventing we have for you the filters specially maded for W164 slow-bitrate CAN with SingleWire working future. Overwise you must found and fix mailfunction on car CAN bus using some special tools, as example - Star Diagnosis (CAN bus System Diagnosis option in StarDiags menu).
