At first glance this unit looks almost exactly like the AVN2210p mkII found in the top five list; basically the only obvious differences are red backlighting versus blue backlighting and gold plated outputs on the mkII. Even the description on the Eclipse website offers nearly identical description of both.
However after closer inspection, it can be found that the mkII option includes the Tom Tom travel kit, which allows the detachable unit to be used as a portable and in other vehicles with the needed cables and mounts.
If a person doubts they will even need the travel kit and red is OK for their dash, then the savings will make this unit a best buy in their eyes.
