15016Re: [tracker2] Interesting --beacon problem between Nuvi 350 and OT2
- Dec 12, 2012I've run into something like this before. What firmware version is your
nuvi running? IIRC, there was a bug in one version that related to
message acknowledgement - the nuvi tells the tracker when there's a
message and gives it a unique ID, but the tracker also polls with a
catch-all ID in case it missed the announcement. The nuvi responds with
the message but then the tracker only has the catch-all ID for it and
ack'ing that ID doesn't properly remove it from the queue. At least
that's how I remember it - it's been a couple of years.
More recently I've seen at least two cases where a message seemed to get
corrupted in the nuvi's memory and also wouldn't ack. The only way I've
found to fix it is to use the maintenance menu (hold down the upper
right corner of the touch screen while turning on the nuvi) to clear all
