Re: Anyone know how to update an old Loran database?

Here is a response I received from someone at GarminAT:

Hi Tom,

Sorry but there is simply no means to update the data.  The required
equipment to "burn" the data to the eproms is not generally available.  Even
if it was, the format of the data is proprietary and not available to the
public.  With the age of the eproms it's very normal for at lest one of them
to not accept data any longer as well.  Once you were to try to load, and
fail, the unit would be rendered useless.  The proms are no longer available
from any source so it just isn't worth the time or effort.  I can only
recommend that you simply continue to use it as it is and load needed
waypoints as user created waypoints.
