Welcome aboard JacketsII
The NavNet 1 and NavNet vx2 will share radar, sounder, GPS, and NMEA0183 through the network. But the charts for 1 and vx2 will not be shared. The charts in the NN1 will share with each other and the charts for vx2 will share with each other. When you add the vx2 displays you will have to reprogram the network through the vx2. If you have any questions on how this is done please contact our tech support group or contact a local dealer.
