My 2005 2620 died recently.
I first purchased a new Garmin, then discovered my Android 5" phone worked nearly as well as the new Garmin. (Sygic does not speak the name of the next turn street.) The Garmin was returned.
I use Sygic software which now will cost about $40 for North America maps (Tom-Tom). No broadband data needed because the maps are stored on the phone.
Updates appear frequently at no cost.
One license allows installation on all owned Android machines like wife's phone and our shared tablet. So plenty of backup GPS machines at no additional cost.
