I've got a few questions on networking and installation on some lowrance units. I've got two HDS 7 touches and 1 HDS 5(old style I believe gen 1) as well as the structure scan module. One of the 7s is already hooked up and installed into the structure scan. The 5 is on the bow mount. My question is once I install my other 7 touch can I network all three together even though the 7s are gen 2 and the 5 is a gen 1? If I can, will I be able to get away with using one map card in the primary unit ( one of the 7s) and still be able to see the map card data on the other two units? Also, if I am correct all I need to network the units together as well as my motor guide xi5 is the NMEA 2000 network kit or is there more to it?

As as far as installation goes, I am wanting to throw the other 7 touch I bought as an in dash/console mount. Is there a special bracket on the market for that or will just the stock bracket work that comes with the unit? I looked and couldn't really find anything different as far as a bracket to mount it in the console. Thanks for the help!
