    Sorry for the delay

    Partnumbers are under group 0 in the ETKA, parts for telephone system. PR codes PR-9IH/9IJ.

    In the case of a Tiguan AD, you will need:

    - Center console (which has a slot for the charging interface) 5NB863241D suffix RM5 of 82V (dealer can tell you which color you have) (LHD model)
    - Phone/charging interface 5NA980611
    - Two-way amplifier 4N0035456 and two plastic fasteners N90536901
    - Contact housing amplifier 8E0971832
    - Contact housing phone interface 4B0971978B
    - Contacts for both contact housings and the pins that go into the MIB unit are the same. I used the TE 963715-1 ordered from Digikey which is the original connector also used by VW. You will need a suitable crimp tool for 0,5mm contacts which can be a pain to find though. Alternatively you can used VW's repair wires which you solder onto the colored wires, you'll need 11 of those then. The dealer can tell you which repair set wire you need when looking up one of the contact housings.
    - Fakra connectors, coax cable and crimp tool, or prefab cables from the ETKA with universal connectors on them.
    - Fancy tape to wrap your additional wiring and to fix this to the existing loom, used some BMW tape i had laying around which is the same as the one used on the VW wiring loom. Do not use cheap isolation tape and DEFINITELY DO NOT use zipties. Most wires in the wiring loom are 0,35mm and zipties will damage these


    I wanted to keep it OEM style and all factory style antenna positions were already taken (roof aerial for SOS module and both LTE antenna's behind the rear bumper for the discover pro's SIM card) so I ordered another LTE antenna 3G9035534 and made a bracket and mounted it next to the rear right antenna behind the rear bumper. I had the bumper off for retrofitting the TPMS module anyway.

    Ordered some 0,5mm wire in the same colors as used OEM. Also ordered a fakra crimp tool, RTK031 coax and a shitload of color coded plugs. Not really reasonable for the one time retrofit, but i had the RNS510 in my previous car stolen a couple of times and the way most repair shops do some tearjerking job with repairing those fakra connections sucked, and i decided to get the real stuff. The tool set me back a whopping €500 but even my local dealer has asked me to pass by to perform a quality repair on a vehicle with a stolen radio two times now. So it's on its way to paying for itself hahaha. Anyway, got the tool from Quaestum, but there are also prefab cables in the ETKA (in the vehicle list, select EL = Elektrische Verbindungselemente).

    Anyway, so:

    - LTE antenna behind rear bumper. If you lack the premium phone kit or the SOS module, either the LTE antenna '2' (rights side behind rear bumper) is missing, or the roof aerial lacks a phone connection. In either case you can mount the LTE antenne in its OEM spot behind the bumper or swap out the roof aerial for one with a phone connection and use that.

    - Amplifier behind right luggage compartment cover.

    - Swap out center console (remove old one and then pull wiring before installing new one).

    - Insert interface

    - Between doing all this pull wiring.

    Wiring:

    Amplifier:

    - pin 1: Power. 0,5mm red/blue to fusebox (interconnects with the same colored wire from the interface)
    - pin 2: Ground. 0,5mm brown to ground (i connected it to a bundle of ground wires in the loom near the amplifier)
    - pin 3: Power on signal from infortainment unit. 0,5mm yellow/red to grey connector (inside quadlock connector) on infotainment unit pin 5 (interconnects with the same colored wire from interface)
    - black fakra connector on amplifier to violet fakra connector on phone interface
    - violet fakra connector on amplifier to violet fakra connector on LTE antenna

    Interface:

    - pin 1: Power. 0,5mm red/blue to fusebox (interconnects with same colored wire from amplifier)
    - pin 2: Power on signal from infotainment unit. 0,5mm yellow/red to grey connector on infotainment unit pin 5 (interconnects with same colored wire from amplifier)
    - pin 3: Data/LIN bus from infotainment unit. 0,5mm yellow/blue to grey connector on infotainment unit pin 11
    - pin 4: Ground. 0,5mm brown to ground (i used another bundle of ground wires near the bottom of the A-pillar)
    - pin 5: No idea what it does. 0,5mm white to 73-pin plug B pin 14 on BCM (this pin is already in use if you have keyless access. in that case this goes to the Kessy control unit. Strip a piece of isolation and connect to existing wire.)
    - violet fakra connector on interface to black fakra connector on amplifier

    If you dont need the connection to the external antenna, you could also skip the whole amplifier and antenna part and just hook up the interface.

    For the install I removed the following (and not necessarily in this order, check the manual):

    - Lightswitch
    - Lichtswitch panel
    - Steering column housing
    - Knee airbag unit
    - Instrument cluster trim panel (needs to go before you can remove infortainment trim)
    - Infotainment display unit trim panel
    - Infotainment display (pulled the wires behind this to the fusebox)
    - Infotainment control unit in storage compartment
    - Dashboard storage compartment as a whole
    - All floor panels on the right side from bottom A-pillar to the rear luggage compartment cover right
    - Side panels of the centre console
    - A/C control trim panel and the controls themselves
    - Shifter trim panel
    - Button unit in center console
    - Rear A/C controls
    - Airduct behind rear A/C controls
    - Centre armrest
    - Rear-right seat cushion

    And a lot of other stuff i might be forgetting. I'll write up a more detailed how-to later on but no time at the moment.

    Coding is pretty easy.

    Unit 5F Information electronics
    Coding
    Experimental coding > yes
    Byte 15
    Activate the following bits:

    - bit 0 Baseplate
    - bit 1 Antenna_baseplate (or don't if you skipped the signal amplifier and antenna part)
    - bit 5 Wireless_charging_availability

    Exit long coding screen, check the 'soft reset' checkbox and do it.

    Oh, by the way. To ross-tech i'd suggest incorporating these bits in the non-expirimental coding screen. Suggested description would be:

    - Bit 0: Phone Baseplate Installed (PR-9IF/9IG/9IH/9IJ/9IK/9IL/9IN/9IP)
    - Bit 1: Baseplate With Antenna (PR-9IF/9IG/9IH/9IJ/9IK/9IL/9IP)
    - Bit 5: Baseplate With Wireless Charger (PR-9IH/9IJ/9IN/9IP)

    So thats it, sorry for the incomplete info but i'm writing this down mostly from memory.

    I'll add some pictures tomorrow.

    Enjoy.

    My Superb (3V5) came with the "signal amplifier" from the factory. Could I then just swap out the insert in the center console for a model with "signal amplifier" AND QI charging (which of course needs to be wired)?

    I cant think of a reason why not, assuming the slot is the same. But there are enough images to be found on google.

    You would need to test if the pin 5 connection to the BCM is needed, and if it is, figure out if and how plug B/pin14 is wired now (or could be wired in a full option car) and if it resembles anything like the VW’s.

    The slot is the same, since QI charging is available as an option for MY17 (mine is MY16). My car does not have KESSY, so I would assume the slot on the BCM is free at the moment. I will keep an eye out on eBay if anything interesting shows up

    If its available as an option on your car, then anything i said about wiring pinout (apart from the interface side, thats probably the same) is irrelevant and you should check the wiring diagram.

    I have taken inspiration from this thread and retrofitted the baseplate for the phone into my Golf, which fits into the armrest storage compartment. the concept is the same, it has the antenna amplifier but no wireless charging.

    honestly I did not use the OEM antenna, instead I bought a generic 4G/LTE antenna meant to be sticked on the windshield with double sided tape. well, I am now left with a "Telephone Antenna - Electrical Failure" error when scanning the car.

    I am now wondering where the problem could be. is it the baseplate? is it the amplifier? is the electronics so cool that it can somehow detect that the antenna is not the stock one?

    How did you code/adapt 5F for the baseplate? I have this baseplate and amplifier wired up to the 5F but no antenna connected yet (original sharkfin waiting for install). I've only coded it in 5F as a Drive2 article instructs but as there is no appropriate DTC in my unit, I'm suspicious it would rather need adaptation changes - which (if any) did you change?

    bit 1 ON

    no adaptations needed...

    As far as i know, the antenna amplifier and the amplifier with QI charging fit the same slot, so if i had a car with none of these, i would go for qi charging as well...

    they don't, at least not in the Golf.

    5G0 980 611 (antenna only) goes into the armrest, while 5NA 980 611 (also charging) should go under the forward console compartment, but not under mine. I bet the compartment is different when buying the option from the factory.
