The Quick Verdict
Get the MGI Zip Navigator AT. It lists at $196 less and is about 2 lbs lighter to load, and it matches the GPS+ on twin 230 W motors and downhill speed control. The MGI Ai Navigator GPS+ is worth the premium if your course doesn't have a separate GPS unit and you want one built into the cart — a 4-inch touchscreen with 40,000 courses on board is real, and not having to clip a device to the handle matters to some people. But if you're already carrying a GPS watch or rangefinder, you'd be paying the extra $196 at list for a touchscreen you won't use. Check price at Amazon →
What They Have in Common
Same brand, same warranty. Both run a 24V lithium battery good for up to 36 holes (MGI's GPS+ product page states only the battery's name; the up-to-36-holes figure comes from MGI's comparison chart, dependent on conditions), both use MGI's Zip fold, both carry a full-directional remote with a gyroscope, and both include an umbrella holder and cup holder. Three-year manufacturer's warranty on each.
Where They Differ
Built-in GPS
The GPS+ has it; MGI lists none for the AT. That's the whole comparison in one sentence. The GPS+ packs a 4-inch touchscreen with 40,000 courses — no phone, no separate device. If that's something you'd otherwise pay for separately, it pulls $196 closer to being a wash. MGI claims a remote range of over 110 yards on the GPS+; they don't publish a remote range for the AT, so those two figures can't be compared.
Downhill control and motor transparency
The AT publishes twin 230 W calibrated motors and lists downhill speed control as a feature on its product page. The GPS+ has the same twin 230 W motors and downhill speed control, plus an electronic park brake, but MGI lists those only on its 2024 comparison chart, not the GPS+ product page. MGI states no brake for the AT.
The AT also has dual swivelling front wheels and all-terrain rear wheels, plus a foldable rear fifth wheel. The GPS+ runs a five-wheel design with a swivelling front wheel. The AT's bag retention is described as adjustable bag support; the GPS+'s as an adjustable upper bag support with straps and a lower bag strap.
Size, weight, and the trunk question
MGI gives each weight both without and with the battery. The GPS+ comes in at 33.29 lbs without, 38.99 lbs with. The AT is 31 lbs without, 37 lbs with — 2.29 lbs lighter without the battery, 1.99 lbs lighter with it.
The folded story flips. The GPS+ folds to 24.4 × 18.11 × 15.35 inches — about 3.9 cubic feet. The AT folds to 28 × 19 × 17 inches — about 5.2 cubic feet, a gap of 1.3 cubic feet. That 28-inch longest dimension on the AT is the one that matters; if your trunk's hatch clearance is under 28 inches when measured flat, the AT won't lie down. The GPS+ at 24.4 inches on its longest side gives you more clearance. So the AT is lighter to lift; the GPS+ takes less space once it's in.
Price
The AT lists at $1,699. The GPS+ lists at $1,895. A $196 gap at list.
Who Should Buy Which
Get the MGI Zip Navigator AT if:
- You already own a GPS watch, rangefinder, or phone app and have no use for a built-in screen
- Your course has elevation changes and you want downhill control stated on the product page rather than a comparison chart
- Trunk space isn't your constraint — the AT folds 1.3 cubic feet bigger
- You'd rather take the $196 lower list price and put the difference toward something else
Get the MGI Ai Navigator GPS+ if:
- You don't own a GPS watch or rangefinder and want 40,000 courses on the cart itself
- You want one device fewer clipped to the handle — a 4-inch touchscreen with 40,000 courses is a real thing, and you'd actually use it
- Your trunk is length-constrained and 24.4 inches fits where 28 doesn't
- The GPS justifies the premium for how you play
The Bottom Line
The AT is the default here. It lists for less, puts its motor specs and downhill speed control on its own product page, and is about 2 lbs lighter when you're loading it after the round — 2.29 without the battery, 1.99 with. The GPS+ has one real argument: a built-in GPS screen that's genuinely useful if you'd otherwise be buying one anyway. A battery rated for up to 36 holes on each is two rounds on paper. Same warranty, same fold mechanism, same brand — the difference is the screen and the $196.
