Narrative:

The relatively new garmin GPS 750 was set up by the pilot and his owner pilot partner. We loaded and activated the unit direct to ZZZ. We were careful to push the button to eliminate the previous flight plan. The unit told us to fly 354 degrees. The heading on our ipad was correct around 270 degrees. We then went to a direct function and flew to ZZZ. The tower controller queried our heading initially 354 degrees. The GPS 750 is a very difficult unit to learn. My partner and I have watched all internet training; read manuals etc. While we were departing; the unit identified ZZZ1 as ZZZ. We have notified the avionics technician where the equipment was installed months ago. It is very difficult to download new data on the computer. Often when the avionics personnel [do the] download we still get incomplete data renewal. Garmin is very hard to talk to or reach. There needs to be better training availability in an airplane.
