The Screens and head units are designed specifically for the vehicle.

If you replace any of these with an aftermarket replacement, expect to lose vehicle options including display info and communications with the car's other systems that may usually be displayed on the screen. The units fitted to the Dispatch (Jumpy) will vary and are usually Fiat units as were co-produced with FIAT. Any aftermarket unit that you fit - even with the harness adaptor that you may need, will very likely NOT function with the multifunction screen, as that incorporates a separate ECU. It won't work with non-compatible units.

Does it impact parking system also? because when put i reverse gear, no beep at that time. When you turn parking system off with button, and on again, pops out in dashboard warning light. So that all problems start with aftermarket multimedia? Thanks again for help

Yes, it does. The head units are not just multimedia / radio units - they display and talk to other vehicle systems on the vehicle's data networks. The parking assistance has a separate ECU that needs to talk to the BSI and to the multifunction screen / Head Unit ECU and has to be able to interpret and display the data correctly - if you have a different unit don't expect it to work. The vehicles operate on several multiplexed CAN BUS networks and the data is encoded and sent through the network - the sending and receiving ECUs have to be able to decode the data to work with it. Non-compatible afterkarket units won't be able to do this.

It's why aftermarket systems are not as popular now as they once were back int he 80s! Most manufacturer's offer different levels of equipment from basic radios with bluetooth to full telematics units now because of the system integration with the vehicle safety systems etc.
