Narrative:
A test flight after having a new garmin G5 installed replacing my vacuum instruments. I decided to fly an ILS instrument approach to my home base. Upon departure I noted that my navigation system in GPS mode was having difficulty tracking my course; [so] I decided to fly the ILS as planned to see if there was any other irregularities. I reported inbound and was approved for the approach from the tower and told to report the IAF. When reaching [the IAF] the tower was busy with other aircraft; I waited and reported inbound when the frequency was open. Shortly after my navigation system failed as well as my radios. At this time; I was on a 2-mile final aware of the other traffic; which was landing ahead of me. Having no communication with the tower and not having received a clearance to land I decided to continue; realizing the tower knew I was on final [and] I was aware of other aircraft. As the landing aircraft ahead of me cleared the runway I touched down; relieved to be on the ground. After parking my aircraft and alerting the avionics shop of the failure; I called the tower to explain the problem.
