Following my thread about upgrading to the Lowrance Link 8 VHF I have my Icom ic-m421 available for sale if anyone wants to make me an offer before it ends up on eblag?
I am in the process of getting the unit tested and cleared down so when it arrives it will be ready for install.
The unit hasn't given me any problems, and the only reason for the update was for the AIS the Lowrance Link 8 has.
