The Quick Verdict
Get the MGI Zip Navigator. It lists at $400 less than the Ai Navigator GPS+, and it comes in at 34.96 lbs with the battery loaded — noticeably less than the Ai Navigator GPS+'s 38.99 lbs. The GPS+ is the call if you walk courses regularly enough that a 4-inch touchscreen GPS saving you from pulling out your phone or watch is worth four hundred dollars over the life of the cart.

What They Have in Common
Both are MGI electrics with a full-directional remote, a gyroscope to hold a straight line, an umbrella holder and cup holder included, a 24V lithium battery good for up to 36 holes, and a 3-year warranty. (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.) Same brand, same remote philosophy, same battery claim, same warranty terms.
Where They Differ
GPS and screen
The Ai Navigator GPS+ has a 4-inch touchscreen with built-in GPS covering 40,000 courses. The Zip Navigator has no built-in GPS. If you carry a GPS watch or use an app, that gap costs you nothing. If you don't, you're either buying one or paying the $400 premium to get it baked into the cart. That's a real choice, not a trivial one — a standalone GPS device is a second thing to charge and a second thing to lose.
Weight and size
Both figures are without the battery. The Zip Navigator comes in at 28.6 lbs; the Ai Navigator GPS+ at 33.29 lbs — a 4.69-lb gap. Loaded, that's 34.96 lbs versus 38.99 lbs, a 4.03-lb gap. Four pounds or so is something twice a round at the tailgate, less so on the fairway since the motor is doing the work. The folded story flips: the Ai Navigator GPS+ folds down to 3.9 cubic feet versus the Zip Navigator's 4.9 — a full cubic foot difference. Its longest folded dimension is 24.4 inches against the Zip Navigator's 27.55. If trunk space is tight, that's meaningful.
Motors, brake, and downhill control
Both run twin 230-watt motors and both have downhill speed control. The difference is where MGI says so: the Zip Navigator's product page lists its motors, quick-release braking on the rear wheels and downhill control outright, while the Ai Navigator GPS+'s motor power, park brake and downhill control appear only on MGI's 2024 comparison chart, not its product page. The brakes also differ in kind — quick-release braking on the Zip Navigator's rear wheels, an electronic park brake on the GPS+.
Price
The Zip Navigator lists at $1,495. The Ai Navigator GPS+ lists at $1,895. The $400 gap at list is the GPS, essentially, plus the smaller fold — on motor, brake and downhill control, the two are closer than their product pages suggest.
Who Should Buy Which
Get the MGI Zip Navigator if:
- You already carry a GPS watch or rely on a phone app — the $400 gap buys a lot of green fees
- Your home course has elevation changes and you want downhill control stated on the product page, not a comparison chart
- You're lifting the cart in and out of a small trunk and every pound matters — 34.96 lbs loaded versus 38.99 lbs is real weight
- You want all-terrain rear wheels and a foldable rear fourth wheel
Get the MGI Ai Navigator GPS+ if:
- You want one device handling GPS and the cart, with no watch to charge or app to fidget with mid-round
- You walk courses without a regular GPS solution and the 4-inch touchscreen would genuinely replace something you'd otherwise buy anyway
- Trunk space matters more than lift weight — the Ai Navigator GPS+ folds to a smaller footprint despite being heavier
The Bottom Line
The Zip Navigator is the easier recommendation: lower list price, lighter with the battery in, and its motors, brake and downhill control all on its own product page rather than a comparison chart. The Ai Navigator GPS+ asks for $400 more and delivers one clear thing in return — that 4-inch onboard GPS. If that screen replaces a device you'd buy separately, the math can close. If it doesn't, it won't.
