Does GPS Map have any additional limits on the number of FIT fields in a DataField?

Hi,

Yes, that old chestnut... Disappointed

I have a mature set of related data fields that generate a largish number of FIT fields. I have honed and tweaked the number over time as I work out different device limits (because there doesn't appear to be a Garmin source for this information...).

However...

After seeing no ERA reports for a long time, I have got a series of reports - across three related DataField apps for one specific device all on the same line number, which is (obviously) the line where I create FIT fields. I have seen this before where I have hit some undisclosed hard limit on memory and / or the number of FIT fields that I can create (which I responded to by reducing the number of FIT fields...).

As this is the only device I am seeing problems on and I am aware of it being used on a wide variety of devices, I am assuming the issue is specific to that device... 

So...

Can anybody confirm if there are any specific differences in the limitations on FIT fields for GPS MAP 66 series?

If so, is there any specific information available to me on these differences?
