A touchscreen GPS released in February 2012 by Garmin with custom position of interests and junction view. The screen size is 4.3" diagonally with 480x272 resolution.
The most common cause of signal failure is the environment around the GPS
Make sure you are not in a parking garage, surrounded by trees or overhangs and at a standstill when the Garmin GPS is turned on.
The longest amount of time it takes the GPS to acquire a signal is 5 minutes. These instances occur when you travel more than 500 miles with the GPS turned off or if you are indoors.
