Hi Robert,
Thanks for taking the time to reply. I feel I have so much to learn to understand what I am seeing on SI. I think I won't make any more variables since I have not even updated or set up the units as yet and will stay with the CSI that came with the 899. Since there is a S/W problem, changing the transducer might cause more confusion if I would happen to have a problem with my new unit. I'm hoping to get everything mounted this long weekend so I can play with it. I'm setting up my boat this year so if I can retire next year I will be ready!
Thanks again for your advice,
Ron
