You have to move up to a 700 or larger series units to be able to Ethernet connect them and share any data – and not all of the 700 series units have this capability.
2. Even though the 858c DI (also the 788ci HD DI, 958c DI and 1198c DI) units have the Ethernet connector; they cannot at this time share the DI sonar with a non-DI model unit. The Side Imaging units that have Ethernet capability (798ci HD Si, 898c Si, 998c Si, 1197c Si and 1198c Si) have a different Di sonar and cannot use the DI sonar from the DI model units (788ci HD DI, 858c DI, 958c DI and 1198c DI).
For about $700 you should be able to get a 788ci HD or 788ci HD DI model unit and add the Ethernet connection later (if you want to); otherwise you could go with the 597ci HD DI model already mentioned and keep some of that money.
