Narrative:

I was flying the aircraft back to its home base after installation of a new IFR GPS and new radios. I entered my clearance on the ground; but failed to activate the flight plan. The clearance was ZZZ1 ZZZ2 as filed; but I started out towards ZZZ2. ATC pointed out the heading error that I created. Contributing to this error was the novelty of the new GPS and my failure to dial in the VOR into the second radio or use my handheld GPS. The controller's verbiage on our initial call-up was not what I was expecting and I was tired after a long day going to get the aircraft and doing the required test flight for IFR certification. When filing the flight plan; I used the wrong GMT time and had to refile on the ground before departure from W75. Once I activated the flight plan and headed in the right direction); I was given direct and the rest of the flight was uneventful. Using the GPS simulator is a bit different because it is necessary to activate the flight plan to get the simulated aircraft position to update correctly.

Title: A PA28 PLT DEVIATED FROM HIS CLRED TRACK BECAUSE OF CONFUSION IN OPERATING HIS NEW GPS.

Narrative: I WAS FLYING THE ACFT BACK TO ITS HOME BASE AFTER INSTALLATION OF A NEW IFR GPS AND NEW RADIOS. I ENTERED MY CLRNC ON THE GND; BUT FAILED TO ACTIVATE THE FLT PLAN. THE CLRNC WAS ZZZ1 ZZZ2 AS FILED; BUT I STARTED OUT TOWARDS ZZZ2. ATC POINTED OUT THE HDG ERROR THAT I CREATED. CONTRIBUTING TO THIS ERROR WAS THE NOVELTY OF THE NEW GPS AND MY FAILURE TO DIAL IN THE VOR INTO THE SECOND RADIO OR USE MY HANDHELD GPS. THE CTLR'S VERBIAGE ON OUR INITIAL CALL-UP WAS NOT WHAT I WAS EXPECTING AND I WAS TIRED AFTER A LONG DAY GOING TO GET THE ACFT AND DOING THE REQUIRED TEST FLT FOR IFR CERTIFICATION. WHEN FILING THE FLT PLAN; I USED THE WRONG GMT TIME AND HAD TO REFILE ON THE GND BEFORE DEP FROM W75. ONCE I ACTIVATED THE FLT PLAN AND HEADED IN THE RIGHT DIRECTION); I WAS GIVEN DIRECT AND THE REST OF THE FLT WAS UNEVENTFUL. USING THE GPS SIMULATOR IS A BIT DIFFERENT BECAUSE IT IS NECESSARY TO ACTIVATE THE FLT PLAN TO GET THE SIMULATED ACFT POS TO UPDATE CORRECTLY.
