Mio DigiWalker C320 review: Mio DigiWalker C320


Mio Technology is gaining a reputation for producing some solid portable navigation systems at really affordable prices, and the Mio DigiWalker C320 is no exception. Like the Mio DigiWalker C520 , the C320 boasts a sleek design with a beautiful...

The Mio DigiWalker C320 features a nice wide-screen display and sleek design. It offers text- and voice-guided directions; a split-screen map view; safety camera warnings; and MP3 playback.

The Mio C320 lacks text-to-speech functionality and has a small POI database compared with other systems.

The sleek Mio DigiWalker C320 offers the navigation basics and solid performance at a wallet-friendly price, but you can get more bang for your buck with other systems.

Mio C320 4.3-Inch Portable GPS Navigator


Mio's C320 is a entry level GPS navigator with a conveniently widescreen touch-screen (4.3 inches). Mio price the unit very competitively which may be one of the reasons it has been in Amazon's bestseller lists

Mio C320b Car Navigation System -

The C320 is very similar to the successful C520, minus a couple of features. It represents great value for money at this price point and is ideal for first time users, or those who just want a GPS unit without extra bells and whistles like Bluetooth...

Great 4.3in display, split-screen technology, text-to-speech, excellent maps, sleek design, safety features

Mio DigiWalker C320 Review - GPS


mio digiwalker c320 review: Mio's C320 GPS provides a good balance between affordability and features.

Good battery life, Good use of screen space, Optional TMC Support

Menu structures are still a mess, TMC support is expensive, No Bluetooth support

Mio's C320 GPS provides a good balance between affordability and features.

On the Road with Mio : Mio C320 Satellite Navigation


Leaving the navigation to others can take some of the strain off driving.

Recently I have noticed a trend with portable peripherals that connect via USB. Instead of providing, as part of the standard package, a power lead to recharge the internal battery via the mains, you have to rely on the USB connection to carry out...

"Fundamental flaw spotted on display"


Buy a TomTom.

The large, widescreen display is bright and very clear.

The arrow compass point is incorrect. It has its east/west reversed, so if you're driving South West, it shows South East.

Worth the money


A wall charger would be nice.

Stylish, big touch screen that is responsive.Highly hackable- you can install one of the many mods available(without any hassle, prior knowledge, or risk of bricking the unit). Someone said the TTS cannot be added anymore- NOT TRUE, I just installed on...

The battery is pretty lousy, but since most times it will be connected to my PC or car charger, I will still give it a 5 egg rating
