need to occasionally refresh AIS display

[donjoyce]

I display AIS data on both my TZ2 and 1835 radar. I occasionally notice that the TZ2 does not have all the AIS instances the 1835 is showing. I could get my TZ2 to display the same info by going into the LISTS/AIS menu and doing a "REFRESH".

Having to do this suggests a bug. I've contacted service and sent pictures of both displays showing the difference and they said there must be something wrong with my unit and I should take it in to a dealer. I have low confidence in the local dealer so I didn't do this.

I've now had the good fortune to test this on another boat that had both a Raymarine chartplotter and a TZ2, and guess what, the other boat 's TZ2 has the same symptoms.

Anyway, I'm a dedicated Furuno owner and would love to know who else might have a setup that enables such a comparison. owners of TZ2 units without a comparison are to me simply unaware of the issue. One needs a non-TZ2 unit to compare with to see it.

You must have talked to your local support outside of the USA. Furuno USA is aware of a software bug in areas with a lot of AIS targets with the TZT2. As you describe, many times in these areas you can refresh the screen to correct. This has been verified with Japan and the next software will have a correction.
