Question about Pioneer AVIC-F77DAB incl. DAB aerial

The navigation software is called iGO. Could not start the navigation system after installation. It only worked after a firmware update via USB stick. I suspect that was an isolated case.
Since then, the navigation system works perfectly. Map updates are available via Naviextras.com. These are installed via USB stick or SD card. I find the operation to be quite well thought out.
Surprisingly, the navigation system also displays speed changes in tunnels because it is connected to the speedometer signal.
By the way, I recommend routing both USB cables. Because the two ports differ slightly in the functions that can be used.
Consider whether the F70 model would be sufficient. As far as I know, you also save a lot if you order the DAB antenna separately.
