I have had the Passat since November 2012 and have used it for almost all the long drives that we have been on, except for our last trip to Himachal, where we had to take the Ford Ecosport to tackle the terrain. The Passat is a very comfortable car, good trunk space and has great fuel economy.
We have driven the following routes in the Passat:-
1. Mumbai to Jaisalmer via Ahmedabad and back via Jodhpur, Udaipur and Vadodara in 2013 (2571 kms)
2. Mumbai to Coorg via Pune & Mysore and back via Bangalore and Pune in 2014 (2897 kms)
3. Mumbai to Lakhpat (Kutch) via Ahmedabad, Dholavira, and back via Devpur, Bhuj, Dhordo and Ahmedabad in 2018 (2677 kms)
4. Countless trips to Pune and back as we have an apartment there.
In 2018, we bought a Ford Ecosport. This car has the Sync 3. In a short span of time I was thoroughly enjoying driving this car largely due to the Apple Carplay / Android Auto, which provided me with Google Maps, Waze, Spotify, Apple Music. The Sync 3 also reads messages, whatsapp and one can reply to them without using the phone. Then we bought a Honda Jazz in Feb 2020; the head unit had similar features.
I was seriously contemplating an upgrade to the Passat; the head was saying yes and the heart was saying no. Sometimes, it was the other way around. Then the pandemic struck and everything went into lockdown mood including my thought of upgrading the Passat. The first few weeks of the lockdown gave me time to think whether I should sell the car. The Passat has given me trouble free service (apart from the infamous ABS Sensor replacements) and had been driven only 48K kms. The car has very good features and is very well maintained if only I could upgrade the Head Unit?
Thus began my search for upgrading the Head Unit. I contacted Sugesh of Vagtune, Kochi and he told me that he can offer an RCD 340G+ or better still a MIB STD2 PQ+ NAV. Both are plug & play, except that the MIB STD2 PQ+ NAV unit is VIN specific and the quality of sound from this unit is far superior to the RCD 340G+. The RVD 340G+ is now fitted on the Vento & Polo. Before buying the Honda Jazz, we had test driven the Vento TSI, which had the RCD 340G+ and we found it ok. Being an audiophile, I decided to bite the bullet and go for the MIB STD2 PQ+ NAV. Sugesh told me that I would lose the Climatronic display in the Unit which I ok with. All other features would be the same, with the addition of Apple Carplay / Android Auto and Navigation (he would load maps for me). In addition, since my rear view camera is the old RGB type, he would provide me with a RGB to Composite Video adapter.
The difference between the existing RCD510 and the MIB STD2 PQ+ NAV is below:-
Features RCD 510 / MIB STD2 PQ+ NAV
Touch Screen Yes / Yes
Radio Yes / Yes
CD Player 6 CDs / 1 CD
Climatronic Display Yes / No
Optical Parking Sensors Yes / Yes
Reversing Camera Yes / Yes
Steering Wheel Controls Yes / Yes
Apple Carplay/Android Auto No / Yes
Bluetooth Telephone Yes / Yes
GPS with maps No / Yes
I paid him 50% advance and provided him the VIN of my car. Then started the long ordeal of waiting for the unit to arrive. Due to the ban on international flights, consignments were getting significantly delayed.
I finally received the unit on 24th September after paying him the balance amount, here is what I got:-

Front View

Top View (Unit made by Technisat, Spain)
The unit came with a separate microphone for direct connection to the system, which has A2DP integrated; unlike the RCD510 which has a separate bluetooth module located under the driver's seat.
The Quadlock connector is also different from the one in the RCD510; I was supplied with an adapter, shown below
A separate USB/Aux connector was also provided, shown below
Since I intended to use the original camera (RGB type) of the car, which is integrated in the VW symbol, I was supplied with an RGB to CVBS adapter, shown below
The wiring needed to be done by a person who is conversant with removing panels in cars, so I contacted my friend Rahul Gurnani of Rhyme n Rhythm and we set up a date for the fitment.
In the meantime, I removed the existing RCD510 and connected the MIB Unit to test its functions. The radio, Apple Carplay, Steering controls, Bluetooth telephone & OPS were all working. I did not connect the GPS antenna and since I was not sure of the rear view camera connections, I did not hook up the adapter.
I found that the rear view camera was not wired into the quadlock for the new head unit.
The white connector with the black wire has 4 wires, red, black, yellow & black. From online searches, I realized that the red is 12V+, black is Gnd, Yellow is Composite Video and black is Gnd. Now where to connect these 4 wires?
The connector with the red wire is to be connected to the reversing light, so that the camera gets the signal to operate.
I started searching online for connection diagrams for the quadlock, finally I found this one and confirmed the wiring from Sugesh of Vagtune.
On 3rd October, I installed the new system in the car and found everything operating, except the Rear View Camera and that the OPS display is showing a Polo instead of a Passat.

I would very much appreciate if any of you could guide me in rectifying these two issues.
I have contacted Sugesh of Vagtune many times; he keeps saying that he is very busy and will help me next week - two weeks have passed this way
