I saw where Larry was wondering about the ability to link the GPS data in a main console unit to, ex. a bow unit, and what it would take to get this done. I'm not totally sure, but Lowrance has a new product apparently does this and more including access to all the boat functions such as engine functions etc. Go to www.lowrance.com and look at the graphics near the top of the homepage. There is one on the left that refers to Lowrance Net. Click on that for more information. Don't know what they mean by affordable but I believe this system will get the job done. Best to all.
