FAQ

Q: Will this interfere with my compass?
A: Yes, it can if mounted too close. Keep the VK-162 at least 12 inches from your magnetic compass. USB devices contain components that generate small magnetic fields. This is normal for all USB GPS modules — not a defect. Mount on your glareshield, kneeboard, or side window, away from the compass.

Q: Do I need this if I already have an internal GPS?
A: Not usually. The internal GPS works well in most aircraft. The external puck helps if your Stratux is mounted in a metal-heavy location (like a bag or under panel) where the internal GPS struggles to see the sky. Most pilots in fiberglass or composite aircraft don’t need it.

Q: Why does external GPS sometimes take a long time to lock?
A: All GPS modules need a clear view of the sky. First lock after the unit has been stationary for a while (called a “cold start”) takes 2–10 minutes. Subsequent starts are faster. Tip: always give your Stratux 5 minutes of pre-flight power-on time outside the hangar.

Q: Is this the same as the internal GPS module?
A: No. The internal GPS (part #3047) mounts inside the Stratux case. This unit (VK-162, part #3088) connects via USB and mounts externally. The GPS chipset is similar, but placement changes reception.
