- Truck-specific features are excellent and more than any other unit.  Truck routing and maps are very good.  
- This brand is the easiest to learn for "non-techie" drivers because of big, clear buttons and logical program layout, yet it still has EXTENSIVE truck features.
-  The sheer amount of information that is displayed on the screen while navigating and the ability to obtain deeper info or addition functions with only one or two taps is very well designed from a user-friendly standpoint on all models, especially 7".
- 520 and 720 models have Wi-Fi capability.  While some drivers do not have "hotspot" capability on their smartphones, or own a wireless cell device, those that do will find the weather, live fuel prices, live local search, and optional enhanced live traffic options to be very good.
- The "TND Dock" application for PC and Mac is easy to use and contains many computer-based enhancements to the GPS overall usefulness.
* Calculation speed is not a disadvantage when first calculating a route.  But, if your planned destination is far away (>1000 miles for example) then the recalculation speed when you choose a different turn than the one on the screen can be a factor in terms of  how many seconds before it is ready to present your next turn info.  The 520 & 720 models and the "fast recalc" option turned on mitigate this issue as well.
** Power socket where the cord plugs in is a weak link on 710 model and the external GPS antenna socket on 510 and 710 models needs to be more rugged.  However, the new ruggedized hard rubber outer shell of the 520 & 720 models and better power connection is more appropriate for semi truck usage than previous models.

Comments: -  (UPDATE!:  ALK technologies was purchased by Trimble in 2013.  They converted this GPS to an APP for phones, laptops, and tablets.  There will NOT be any map updates to the PC Miler Navigator series of units.
-  The clarity of the roads around you is the best that we have seen, including having icons on the streets where a low clearance is located.  Display of street names around the vehicle and road location detail when zoomed out are standout points of this brand.d.
-  For budget-minded there is a 4.3" and refurbished versions.  In our tests the 4.3" is too small and not loud enough though.  However, it is a low-cost entry-level choice.
-  The touchscreen can be very sensitive, specially on the 550 model, which can make it easy to miss-tap a button.
-  This brand will be the lowest price, but at the expense of many of the features offered by competing brands at this point.
*  Although these models do not have nearly the array of truck features that Rand and Garmin have, it is a solid truck navigation unit when you have set the truck and road options correctly for your truck.  It's good for truck navigating but without the extra bells and whistles.
** our stability rating got lowered from 9 to 8 because when the state mileage logging is turned on it can be prone to lockups at moments when you go through tunnels or an area that blocks the sky from GPS signal.  Turning the state mileage logging off eliminates this issue though.

The 560 is a marked improvement in our opinion over the original 465T in terms of screen size and features.
-  Garmin has stepped up the feature set with a "grid-style" driver log screen, multiple drivers for teams, and fuel and load logging.
-  We do not find that their bean-bag mounting style is appropriate many many truck drivers who prefer a suction-style mount due to the way that most semi trucks are configured.  The power plug goes into the mount and not into the GPS itself.  If the bean-bag style mount is not an issue for you then this power method makes it easier to remove the unit from its cradle without having to unplug a power cord.
-  The Garmin touch display quality and overall hardware are very good and we have had no issues with durability.
-  The price is higher for the Garmin unit than "same-sized" competing brands, especially for the "lifetime" maps versions, but it can be argued that Garmin's high quality of hardware and tech support is part of that trade.
-  For fans of previous Garmin-branded GPS who are used to the Garmin interface and associated computer updater software, this is a good choice.
*  Garmin overall truck route data especially inside of urban city streets is not as mature as the other two reviewed in this page, but is by far better than a car-specific GPS.
**  We are not fans of Garmin's method of making you choose a state before entering an address.
