I have a Pioneer AVH-X3700DAB. It does DAB, bluetooth streaming, USB, AUX and makes and receives phone calls.
I got the window DAB aerial from halfords along with the harness adaptor and fascia.
The hardest part was finding the right fuse to get the ignition switch.
I’ve also wired up a reversing camera.
I’ve not had any problems with DAB reception it’s been flawless. USB stick access can take up to 10000 tracks and bluetooth connectivity it great.
I’ve not bothered with a sat nav cos I use Copilot app on my phone.
