Summary: The Amazon product information page is incorrect for the S401 (Magenta trim). The title lists M400 but SKU and and only parts of the technical details are for the S401. The info below is from the MIO website for the S401: The sleek new Mio Moov S401 breaks new ground in personal GPS navigation.
Summary: I BOUGHT THIS GPS BECAUSE WE TRAVEL CROSS COUNTRY OFTEN. I HOPE THE MAPS ARE MORE UPTO DATE THAN THE ONE FOR MY TOWN, IT SHOW'S AN EMPTY FIELD WHERE THE MIDDLE SCHOOL IS LOCATED, THE SCHOOL HAS BEEN THERE FOR AT LEAST 4 YEARS. ALSO BATTERY LIFE ALMOST NONEXISTENT. BUT OVERALL NOT A BAD BUY FOR THE PRICE.
Summary: Mio Moov S401 one of the best GPS navigation. New Mio Spirit software interface featuring cleaner is great, uncluttered map views and search enhancements with fewer taps and clicks to more quickly find what you’re looking for. Text-to-Speech (spoken street names), Lane Guidance and a large 4.3”, anti-glare widescreen display, you’ll never miss your destination.
Summary: This is a more updated version of a GPS we have had for several years. It's easy to use, has plenty of information. I used it side by side with my sister's Garmin and the Mio was more accurate and user-friendly. I especially appreciated the fact that it gave clearer instructions more frequently. The Garmin often waited until it was too late to follow the directions - not so with my Mio.
Summary: i got one of the Mio g.p.s systems 2 years ago for Christmas I've used mine numerous times and found it a handy tool when i didn't know where i was going or going on vacation it guided me on a 6000 mile vacation that would have been impossible to imagine with out it so i bout each of my 2 children one of there own it was a great price through e bay and they are easy to program and they speak clearly so you can follow directions
Summary: The Mio Moov s401 works fine but the maps are outdated and the website doesn't give you the chance to purchase updated or new maps for the device. It would be great for an area that doesn't change much but I'm in Alaska and the roads here change every year.
Summary: This review is from: Moov S401 4.3in. Car Navigation System I feel very comfortable with Mio GPS C310X and C320 after owning them for several years. So, I decided to move to new S401 and S501. I bought them at the same time. What a disappointment! It seems that the products have removed many important features that make Mio GPS standing out from other competitors such as (1) Adjustable smart zoom settings. S-series is a fix zoom level, no tilt level on 3D.
