Lowrance HDS 7 Gen 2 touch wiring question

[Garbagetruckman]

Bought a boat a few years ago that had HDS 7 Gen 2 Touch at bow and at front. What other Lowrance units are compatible with the wiring/cables? I'm wanting to upgrade but I don't want to have to rewire everything. I saw an HDS 12 Gen 2 Touch on Marketplace, but wasn't sure if it would fit.

Thanks for any information.

These can all use the same transducers and powercable:
HDS Gen 2 Touch
HDS Gen 3
HDS Carbon
HDS Live.
Keep in mind that new or larger units have higher draw, so ensure wiring and fuse is up for that.
