Want to add a unit to the bow and link to the HDS Touch7

[chipperoonie]

I have recently installed a new Lowrance HDS gen2 Touch7 on my 2000 Nitro.  I love this thing and want to add another unit at the bow for downscan and to link with the console unit.  I would like to avoid spending another $1000....Any ideas?
