Unless the T3-301 receives a new packet from that call sign it will stay there forever. For example somewhere down a ways on my Nuvi list of stations is an American trucker my Nuvi saw a few months ago. If that's what you're thinking of? I just delete those old out of date stations from my list. Or clear the entire list and start fresh occasionally.
Plus if I send a message it keeps sending until acknowledged rather than so many attempts. Not sure how to deal with this.
There could be several causes to this.
I have the case where suddenly the Nuvi doesn't seem to acknowledge that a message has been sent via the Dispatch manager to the T2-391. That is if I key in --info as a message the Tracker keeps replying by sending me messages every few seconds until I delete the message from the outgoing msg queue. I first noticed this behavior when I keyed in a --beac message while driving. An hour later I realized I had been beaconing my position every 10 seconds. Now I do need to see if updating the Tracker2 firmware will fix this. Alternatively I need to clear all the data from the Nuvi 350.
Or it maybe be that the recipient station/device is no longer available or within range of a digi or igate to acknowledge receipt of the message.
Or that your T3-301 can't hear and decode the packet from your nearest digi or igate. I've found that while mobile the T2-301 can't decode packets when I'm about 20 miles or more from the nearest digi. Although the digi's can receive my packets up to about 40 miles depending.

It doesn't come with a case. It's intended mostly for embedded
applications, where you want to put the board inside a radio or a
balloon payload, or otherwise just don't need a big case and bulky

normal behavior. Message ACKs are tricky - I think there may be a bug
in the ACK code but the nuvi is sometimes weird about how it handles the
message queue. I've been doing some testing on that lately.
