I looked for a previous thread on this problem but didn't see one. I have a 998c SI HD that was professionally installed on my bay boat one year ago. Until recently the unit has worked great, no problems. Now I get a screen message "No GPS connection" about 15 minutes after turning the unit on. I've fished 3 times since this first happened and the GPS appears to reconnect briefly every once in a while after the initial message. A few times the receiver appeared to reconnect but there was a message "No GPS Fix". I'm thinking either a corroded connection somewhere or I need to replace my receiver. Since I didn't install myself (and this is my first unit with external GPS receiver), I'm not familiar with how everything is set up.
The puck is mounted on the center console dash and all wires going to the unit are coiled underneath. I've unplugged and reconnected the unit several times but the result is the same. My request is your suggestion on where to go next.
Are there connections between the puck and the unit I can check? Access beneath the console pretty much sucks in my boat. If there's nothing to check I don't want to waste time cutting zip ties and undoing a bunch of stuff for nothing.
Are there connections inside the puck I need to check? Or should I start looking for a replacement GPS receiver and cable?
Thanks in advance for your help.
