I read through other posts and see that some users have had a similar problem to mine but updating their Nuvi & OT2m firmware solved their problems.
In my case, I'm running two brand new Nuvi 350 / OT2m stations (one for my car and one for my wife's car) and both stations have been updated to the latest versions. For the Nuvi - that is version 6.20 and for the OT2m I'm on firmware version 55076. Unfortunately, the updates haven't solved my problem. I can send a message from Nuvi 1 to Nuvi 2 just fine but then Nuvi 1 says "Sending" and eventually, I receive the message on Nuvi 2 again, and again until I delete the message from the outbox on Nuvi 1. I have also noticed when I try to send a message from Nuvi 2 to Nuvi 1, I never receive the message on Nuvi 1. This may be a clue that this problem has something to do with acknowledgement perhaps. I have checked through the config settings on both OT2m units several times each but can't seem to find anything wrong with either unit's configuration. Both sets of radio cables I'm using came from Byonics and they all seem to be transmitting / receiving just fine because the two different call signs are showing up on both Nuvi's as stations heard. There are no other APRS stations within radio communications range of my home so I know that the only way the callsigns show up in the list is if the two stations digipeat each other. Transmit on both radios is set to Extra Low as they are in the same room with each other and the receive volume is set to about 50% of max volume on both radios. I've spent about 4 hours or more trouble-shooting this evening but I've tried everything I can think to try. I'm hoping that someone has come across this problem on updated equipment and found a solution. I'm sure it is probably some sort of user error but I don't seem to be able to figure out what I've done wrong. Any help or thoughts on this are appreciated.
