Just some info for anyone that has a Northstar 6100. They are discontinued and are no longer supported by Navico. My 2 year old unit froze a few weeks ago so I called them up. They are offering a trade in for all 6100 units including depth sounder and radars. You can choose either the Simrad NSS or NSE and components at a very good price. Give them a call before they discontinue the offer.
Call or msg me if you want more details.
