Here is the list of components that I purchased:
1. Vanku 10 Inch Android 10 Car Radio Moniceiver - 1 DIN unit.
For 4G function, I am using Fraenk SIM card with 4 GB Data included for 9.99 EUR monthly, which is not bad, especially as I am mainly using data for Google Maps and Waze.
For those who want to have Steering wheel joystick to be working with monciever, you need harnessing kit, and this one works too:
I am really super happy with overal performance and functions, and of course, now having DAB+, it is really not comparable with anything from before.
In total it took me 1.5 hrs to assemble all, where biggest time I dedicated on passing GPS and WiFi antenna cables, USB cables (There are 3 in total), and DAB+ antenna to DAB+ receiver, which is sitting in front compartment.
