If you stack this device up, even against Navman's own and more expensive MY series there is not much missing from the list of options.
4.3' Resistive Panel with a 480 X 272 resolution is a good start and coupled with an improved Navman interface that makes selecting an option and data entry quick and logical your basic navigation needs are well met. Screen response is satisfactory for most functions; though a little slow if you want to navigate a map screen by finger.
The unit itself is unremarkable, with a rather simple black finish, and micros SD port. The non-integrated Navman mounting system is a much better solution than other brand budget lines with the mount housing the power connection, whilst still allowing for quick decoupling and removal when parked.
The EZY series says no to multiple English voice options, but yes to just about everything else. Spoken street names, a database of over 640,000 points of interest, school zone detection, 3D junction views and multiple route options give all you need to get places. You will want to adjust the alerting options to tone down the barrage of speed, safety camera, railway crossings and accident black spot warnings that can become more distracting than informative at times.
The EZY45 is a well-priced workman like device that provides the navigation essentials and more that most will be looking for in a dedicated sat-nav unit.
