    Hi again;
    Rick is right in respect of Non-complient receivers of whatever make. My
    GPS is a 7 year old Trimble Ensign which is non-complient but
    "Upgradable". (This means "Dont chuck it away but don't use it for real
    on Saturday night!). After Rollover I can reset the receiver by a
    process which will wipe all the existing memory and this includes all my
    recorded waypoints! When I turn it on again I will have to at least 30
    mins for it to copy down all the new almanac data.(If the GPS is moving
    while this is being done it could take a lot longer, doing this in my
    car travelling south at 70 mph it took an hour to aquire a fix).
    Trimble has a good website at  for more
    details about their own products and wnro in general.
    Another discusion group specific to GPS can be found at the Royal
    Institute of Navigation website
