Superb 2 front OPS retrofit

Hi there,

I've been a Superb 2 owner for good three years now and from the time I purchased the car I was thinking of retrofitting the front OPS.

Few details on the car:

- Superb 2 3T5 2012 Combi

- 2.0 TDI 103 kW (140 HP)

- DSG

- Elegance

- Amundsen+ RNS 315 Navigation unit 

My car only has the rear OPS which was factory fitted. I was searching online for upgrade kits and have found the following options:

CarSystems.eu

CarsEquipment

Aliexpress

On the pictures, all of the systems look the same to me, does anyone have any experience with these kits from different vendors? The price differences are quite big, I don't mind paying a bit more to get a quality product but if they are all the same in the end I would choose the cheapest option.

I have searched the forum and didn't find any specific guides for front OPS retrofitting on a Superb 2. What I found online, which I think will help me in the installation process are the following instructions:

Golf 6 OPS retrofit

Superb 2 RVC retrofit

Touran OPS retrofit

I've also found some maintenace manuals where I hope I will find some details on hoe to safely remove the panels in the car to install the new wiring. Are there and PC programms with interactive maintenance manuals, such as bodywork thing visible in the Golf 6 OPS link? Does anyone have any experience in retrofitting stuff in Superb 2? I need a bit more details on the installation itself, I wan't to have a whole picture in my head from start to finish before I start tearing my car apart. The wiring diagrams from the kit suppliers are poor (Aliexpress link) I am not an electrician so I have a lot of questions here, where are the additional sensors connected, to the new 8K sensor module which will replace the existink 4k one? To I need to wire anything to the main electrical panel with circuit breaker in the cabin? If someone has allready installed OPS in their Superb I would be most grateful if you could share the installation manual which came with the kit, if that will make anything more clear to me.

Thanks in advance.
