What we can verify

  • SG-03 is positioned as a USB GPS HUD that projects MPH on the windshield without needing OBD.
  • SG-04 is positioned as an OBD2 + GPS dual-mode HUD. Exact sensor list can vary by vehicle compatibility — check the product page and your vehicle’s OBD support before buying.

We soften unverified “turbo boost / every fault code” marketing claims: treat advanced OBD readouts as vehicle-dependent, not guaranteed on every car.
