Mio Moov M400


It's no secret that GPS prices have fallen tremendously in the past year. Most come in at under $300; and there are plenty of capable models available for less than $200, and that's not even counting the year-or-two-old models that have been discounted...

Very affordable for a device with a 4.3-inch screen and text-to-voice conversion. Accurate directions

Cluttered, sluggish UI. Limited, difficult-to-search POI database. No real-time traffic, lane-assist feature, or speed limit postings

The Moov M400 will appeal to many given its rock-bottom price, but Mio cuts too many corners along the way, and delivers a GPS that's difficult to use.

GPS Review: Mio Moov M400


The Mio Moov M400 is priced at less than $100. What can you get in a GPS at this price? Just enough.

Mio Navman M400 Sat-Nav


If you're after a functional budget sat-nav for European travel, or even just everyday use, the M400 is a bargain.

The Mio Navman M400 is no feature-rich powerhouse. In fact, apart from the free search facilities for addresses and POIs, it's actually a bit behind some of its competitors in this respect. But then there's the price. We were particularly impressed by...

В Mio Moov M400 нет серьезных минусов, придраться можно разве что к очень простой комплектации и отсутствию дополнительных функций. Среди плюсов отмечу хорошее качество экрана, отличную сборку и приятный внешний вид. Программа MioMap не вызывает...

Mio Navman M400


The Mio Navman M400's picture tagging skills don't make up for an otherwise last-gen satnav - unless you need to go abroad

Cheap, European maps as standard

Mediocre build, Mio's mapping is flawed

Mio Navman M400


The Mio Navman M400 satnav wants to stamp out all those myths about pricey GPS units. It's a fully fledged, 4.3-inch PND with European maps that comes in under a hundred quid, but does it lose anything essential shaving off the cost? The good The price...

If you're not planning on crossing the channel in your car, you might be better off opting for a cheaper TomTom One, but if you know you'll be driving in Europe, you'll find the included maps still make this a bargain. Mio Navman M400 is tagged with...

Good unit.


Will be using this mostly for trips, in and out of state. Pros is very accurate when using NavPix. Found a picture of a lake I use all the time and downloaded it to my Mio from the included software. Just clicked on the picture (geo tagged) then the...

Excellent GPS for price!


This GPS is fantastic, I saw someone complain about the 15% restocking fee. You don't need to worry about that if you don't need to return it because its fantastic. Everywhere has that restocking fee and its senseless to rate the product poorly because...

Can't be beat for the price


Not very good instructions for use. Learned by trial and error. So far I am very pleased with it.
