I have a 1197c hummingbird unit, and I just bought a new Lakemaster chip to run in it. I had been using the Navioics chip before and had not had a problem with it loading the charts,. But using the Lakemaster chip, it sometimes takes 1 minute for it to update the chart. The screen will go white and then in up to a minute or soo, it will finally put the chart page up. I do not have the latest update loaded on my 11987c, for fear of having trouble with it. I am thinking the last update was 2 updates back.
Do any of you have this problem with Lakemaster chips? I really like the chart, and some of the features it has that Navionics don't.
Any help would be appreciated.
