Magellan recently announced the release of 7 new GPS units with release dates scheduled in September and October. We can thus get our hands on the Maestro 4250 (for around $500) in the 4200 series, which offers live traffic updates, a 4.3 inch display widescreen together with Bluetooth capability. The 4220 and 4200 models will cost less because the integrated live traffic updates feature and voice control will not be included.The Maestro 3250 is almost identical to the 4250 but is $100 cheaper. This is because it has a smaller non-widescreen display of just 3.5 inch. The other models of the 3200 series (the 3200, 3210 and 3220) are similar to the 3250, with the same display but with less features. All depends on the price. The new releases are not that different when compared with the old ones. The only real change stands in the size, which dropped 0.7 inches in thickness. We can also see some minor added features but none of them are that special.
