HifiBerry and GPS Hardware
Posted: Thu Aug 07, 2025 12:33 pm
I wonder if the HifiBerry sound cards and GPS module can be used with HUDIY? also, is there any instruction to setup the gpsd information into Android Auto or Carplay services?
Hello,
We’ve covered this topic in our FAQ: https://hudiy.eu/faq/#toggle-id-11.
In general, Hudiy uses PipeWire for audio which is the default audio subsystem in Bookworm. We’ve seen that HiFiBerry provides modules that are compatible with the Raspberry Pi 5, so it’s likely that this hardware is also compatible with PipeWire.
As for GPS - the Android Auto protocol supports receiving GPS data, and Hudiy provides it via gpsd, if a GPS module is detected on the Raspberry Pi. However, what Android Auto actually does with this data is unclear (we can see in logcat that GPS data is being received by Android Auto).
To be honest, we haven’t noticed any major improvement in GPS signal accuracy when using a connected GPS module.
Unfortunately, CarlinKit dongles do not support GPS data. They also don’t forward navigation maneuver information the way Android Auto does.
