Upgrading the infotainment system of my Volkswagen Polo TSI

What really charmed me was how good this headunit feels in this car. It increased the functionality of the cluster by allowing me to make calls without taking off the wheel, as Google Assistant continues to have issues with my friends’ names.

BHPian fluidicjoy recently shared this with other enthusiasts.

The authentic RCD340 The main unit is a nice radio with native support for Android Auto and Apple CarPlay. The unit also supports rear view camera input and displays OPS system. The touchscreen is responsive and the user interface is fairly straightforward to use. However, this primary unit only relays information from the incoming caller to the Maxidot cluster, even when the Maxidot cluster can do a lot more. BHPian Sarfraz and a few of my friends had already switched to better sounding head units like Composition Media, and most of them were really happy with the tighter integration offered by these head units, and So I ended up selling my RCD340 and bought a Discover Media MIB 2.

Main features of the Discover Media MIB 2 main unit:

(Includes CD with SD card, USB and AUX input)

  • External USB for Android Auto and CarPlay
  • Roof mounted external microphone for better phone calls
  • Better integration with Maxidot Cluster – Navigation, phone logbook, media playback, current track, etc.
  • Support for radio station logos.
  • Offline VW navigation based on SD Maps.
  • Support for OEM amplifiers, tweeters, etc.
  • Faster processors.
  • Proximity sensor based menu bars
  • Off-road mode, sports stopwatch,
  • Car Menu showing vehicle and trip information like MQB cars.
  • Simultaneous display of OPS and rear view camera.
  • Support for multiple colorful and themed skins like VRS etc.

Radio connector, wiring:

The connector of the RCD340 is a QUADLOCK connector, but the installation of the MIB-2 requires a different quad lock. The USB and AUX ports occupy a separate rectangle in the Quadlock. The microphone wire connects to the blue rectangle which has the camera signal pins at 6 and 12:

If you plan to use a converter for the existing quad lock, there might be a space constraint behind the radio, but with a little adjustment you can still get everything set up correctly. The new microphone is now in my Passat-style cabin lighting and is routed along the A-pillar, which is susceptible to breaking when removing:

By removing the A-pillars, I noticed that the A-pillars now only had two plastic clips and brackets, compared to three previously:

Previous cars would also get a insulation inside those A-pillars, and I managed to get hold of these two gray foam inserts for scrap car insulation. Volkswagen is sure to amuse when it comes to its cost reduction skills.

I installed the USB port by enlarging the slot next to the indirect TPMS tuning button (now gone) and the wires were routed by removing the glove box:

The USB and AUX port does the trick, but unfortunately cannot be installed as well as the TPMS button. Now the Polo has an OEM wireless CarPlay nickname, which my parents love to use. My dad joked that he wanted a wireless charger and a heated seat afterwards.

OEM 6R Shark Fin Antenna:

Next, I proceeded to install the OEM shark fin antenna with provision for GPS. Frankly this OEM shark fin antenna is not a perfect shark fin and combines the original rod with a shark fin base.

However, the reception of this antenna is much stronger than before. it took more GPS satellites compared to a few other GPS antennas I have tried with this headunit.

Removing the original antenna requires removing the rearmost headliner, and access can be slightly narrow if you don’t want to crumple or crumple the headliner too much:

Using a 21mm wrench I undid the bolt that holds the base of the original antenna to the roof of the car and it’s a little hard to undo without too much pulling and crumpling the headliner:

Once this ring bolt is loosened, the antenna can easily be unscrewed and removed from the top. Remember to disconnect the White antenna connector before removing the old antenna outside the car:

This is what the base of the antenna looks like and this is where the rod screws into:

And this is what the new one looks like and this is probably the only time it looks like a shark:

There are a few other VAG antennas that are smaller and don’t require the use of the old antenna rod, but I figured I’d stick to the OEM specs for now. This is a true 6R platform antenna and also has an antenna for what I believe is a telephone antenna.

I cleaned the mating roof surface and dried it, then connected all the connectors before tightening the antenna:

As usual, a water test was in order and the antenna passed handily:

Experience with Discover Media:

I’m not an audiophile but my first impression with the main unit was that the sound quality was about 20% better than the RCD340, which is frankly not a very good upgrade.

Probably better speakers are what this head unit needs to make it feel right at home. I rarely listen to music at high volume, but the original speakers seem to cry over the 60% mark. This is not something I had seen on the RCD340.

What really charmed me was how good this headunit feels in this car. He increased the Functionality of the cluster by allowing me to make calls without letting go of the wheel, as Google Assistant continues to have issues with my friends’ names:

It’s really nice to see how the offline cards work with the cluster. The turn-by-turn GPS navigation is nice and seamless, and it’s something I would have liked VW to offer with our diesel Tiguan as well:

The map data itself is obviously not as good as Google Maps, but it’s gone crazy. The last time I used a VW card was two years ago, but the one I have downloaded a few weeks ago the Volkswagen site seemed to be pretty much in sync with the conditions in my city for most of the major roads. So it looks like Volkswagen is trying to improve its local map data. The maps can be downloaded from the Volkswagen Global website and simply need to be copied to an SD card.

The navigation function also brings a nice compass on the cluster which indicates with a letter the direction in which I am heading. There is also a dedicated page on the cluster for this compass:

There is a funny story associated with this. I was driving and I found myself on a short signal so I kept my car in D. And I was shocked to see an N in the group. I panicked and thought my car went into N while the selector was in D and almost thought my torque converter gave up. It took me about a minute to realize I was looking at the compass and not the gear selector.

It’s good to have some CD reading since my mom is still an MP3 fan. For the love of the good old days, I played a few of my old Kenny G CDs and they sound so good in an age of low bitrate streaming and buffering services. Apple CarPlay access has been moved to the glove box and now works wirelessly with no wires hanging off the gear lever.

Another nice touch is the Combined OPS and reversing camera seen. In reverse gear I can see the whole screen of the camera and if there is any object approaching then the OPS unit overlays itself at the right time. It really is a godsend and works like a charm:

The latest version of Discover Media also has some extra cheats like a Sports Stopwatch Fashion, Car Menu which shows the Polo with details of the trip, distance to empty, fuel consumption etc. The image shown is actually a Polo with bi-xenon headlights:

It also has a function called Off-road mode which displays the value of the steering angle sensor, the compass and the engine temperature in three separate gauges. It’s good to have the steering angle, but for more experienced drivers it’s not really hard to tell when the steering wheel is straight, but it could be something useful if the Polo had to do off-road. So overall I would say it’s not that useful in town. The Discover Media also comes with support for skins and the Red RSV skin looks amazing in the Polo, but I still prefer the old-fashioned sophistication of the original skin.

Overall, I really like the Discover Media upgrade, and it added to the overall sophistication of my car. In fact, there are so many features and hidden features that every once in a while I hear of something new to activate and try on this headunit.
