    741xs losing sonar

    has anyone had this issue. message on screen stating lost sonar. I have 2 741xs on the console and when the left one{newer unit} looses sonar the right one shuts down. Fished 4 days early may with no issue, then this started 2 weeks ago and again today. I called garmin while on the water and went thru multiple steps to resolve. At one point the left one would not come on. All connections are snug. Garmin tech said it may need the 6.3 upgrade. will do that tomorrow but just curious if anyone else has had the same issue. Interestingly I have a 70s n th bw which hs not been affected All 3 run to GCV 10 which is running the most recent upgrade.... very frustrating

    Run after the 6.30 update and report back.
