[tracker2] hooking up one wire temp sensor

[Ron K7CDL]

i'm thinking of hooking up a 1-wire temp sensor to the RJ12 plug on the front 
to hook up a outside temp reading outside my car. what i'm wondering is when i 
turn this on where does it post it, what i mean is does it post the information 
in the status line,comment line or somewhere else? does it post it to where it 
can be seen on the FMI on the Nuvi 350?
thanks,
