While flying over ZZZ1; I became task saturated due to a malfunction with the avionics. After being called by ZZZ Center; the comms switched back to the previous control frequency as well as the PFD glitching. While I tried to sort out what happened I missed the call from ZZZ Center I veered off course and by the time I got back in radio contact with ZZZ Center; I was in the restricted airspace and had not responded to multiple attempts from ZZZ Center to contact me due to the frequencies flipping and ultimately flew into restricted airspace. After troubleshooting the comms and PFD; I was vectored out of restricted airspace and resumed en route to my destination. About 15 minutes later the PFD turned into a mix of white and pink lines before ultimately shutting off. At this time I made the decision to turn back to ZZZ where I was sure the conditions were good VFR so I could make a safe approach with the failed instrument.
