RouteBuddy today announce the release of RouteBuddy 1.2, a major update to their GPS mapping software for Mac OS X. RouteBuddy provides native Mac OS X support for Garmin GPS devices, and allows users to manage and display their GPS data in conjunction with a set of high-precision, vector-based road maps. Version 1.1 adds support for address searching, improves routing, and introduces a new compressed map format that uses up to 50% less disk space. This release also includes over 20 bug fixes and improvements. RouteBuddy is priced at US$99.50, and requires Mac OS X 10.4 or later.
