Lowrance GPS not working (help needed)

 Hi all. I have just purchased a second hand lowrance GPS LMS 525. I have the LGC-3000 receiver but cannot get the unit to pick up the receiver. I have the T price and cables to suit but still not working. Any ideas? Maybe someone has the same receiver I can try plugging in to rule out my receiver being stuffed.                            Also on another note I have the (HDS 5X gen 2) and cannot get it off split screen. I've googled it but still can't figure it out. 

I would appreciate any help. Cheers

 Make sure you've got terminals on both end of the T-piece which completes the network,  Also pretty sure you can select the LGC antenna if it comes up in the network settings too.

Make sure you have set up a second power supply for the network. 

The LMS wont power the network from the head unit

Both of the above comments are 100%, I struggled when bench testing before I realised that you need to power the network...

Thanks for the info guys. Much appreciated. I followed your advice and wired in a separate power source and it worked perfectly. Huge relief.

I still have the sounder stuck on split screen if anyone has any ideas. It's just been one of those weeks haha.

Split screen ?

 When you say split screen do you mean viewing two things at once (map and sounder) or on the sounder screen full depth and bottom lock (bottom plus a few metres above)?
