Announcement only list for people who own Sendero GPS. Sendero GPS is specialized software and hardware for blind and visually impaired individuals that uses GPS along with electronic maps. This technology verbalizes all the navigation and orientation data, so a blind person can know where they are and where they need to go. It runs on a fully accessible PDA. This list will discuss new software developments, give opportunities for list members to participate in future software development efforts, and inform users when patches or other support items are released.
