Finally got Class B AIS installed. For some reason it was a big PITA. I purchased a pre-owned Garmin unit (talk about being a risk-taker...ha ha)
It received data fine but initially it wouldn't transmit . I finally put the GPS puck on the wheelhouse roof and disconnected the splitter. Once I could see the target on marine traffic dot com I reattached the splitter and put the GPS puck on the front console which is where I want it and the signal kept refreshing so all appears to be good.
I think the real problem was my boat is in a storage yard in the middle of nowhere and the receiving tower is over on the mainland maybe 40 miles away so it took a loooong time for the tower to recognize my signal
I'm guess once I'm on the water I won't have that issue
Definitely worth having an AIS transponder---it's a safety issue on different levels---your family can track your whereabouts on a computer screen, if you have an emergency SARS knows where you are (depending on refresh rate) and last but not least, when you're going through Dodd Narrows or the Yucultas or any tight pass with limited visibility, oncoming traffic with AIS Rx knows your position and heading before they physically lay an eye on you.
And me being the sneaky guy I am, I wired it to a rocker switch so if I want to go into stealth mode, I can turn of AIS Tx but maintain AIS Rx via the NMEA2000 AIS enabled VHF radio
