If you contact support through Whatsapp they should include everything tailor made to your vehicle, fascia, wiring harness, CANbus Module, etc.
I have just ordered today but have been chatting with Support for a few months now and they are very resposive, even in weekends. Very un-chinese like, so can only recommend until now.
Tomorrow the engineer will review my order and vehilcle pictures and select the best combination of hardware for my vehicle.
A Fiat Ducato 2010 RV.
This will replace my aging Dasaita Max10 CP HD, that overheats when the cabin heater is on.
So hopefully the DUDU7 will work great with active cooling in the device, the Dasaita has no active cooling at all.
I will be using Sygic Truck/Caravan, I have been using it for years on all my Android devices, I expect it to run the best on the DUDU7 with all the power it has.
I went for the 11.5" 12G+512G version and might install a few Offline navigation applications as a backup.
The screen dimensions are about the same as the Dasiata 10" screen, 1 cm higher.
