If the GPS loses its copy of the ephemeris it can take 30 mins, or longer, to get locked again. Since the ephemeris is good for many weeks that is a minimum hold-up time in standby mode. > and I hate ANYTHING that needs a user-replaceable component, 5 years > after manufacture.

Given the added NRE and BOM costs of a replaceable battery compared to the current BOM I can live with that. And once again, please forward to the thumbgps list if this gets blocked. Some spam filter somewhere keeps blocking my posts. RGDS GARY --------------------------------------------------------------------------- Gary E.
