[JB11] Dragonfly 4 pro GPS positioning very poor
Hi there
I recently purchased a Rib which came with the fishfinder mentioned above.
On first use I discovered that the GPS position was approximately 400metre off location.
I also noted that the mapping had virtually no detail in it to match my present position.

As the GPS appeared to be picking up most of the satellites for a good fix, I could not under stand why it was so far off locations. I used my mobile to determine that is was approximately 30's off in it's LAT and LONG positioning.

I thought maybe it needed a firmware update or something similar,?
Can anyone suggest why the positioning is completely off and why would the mapping be lacking any sort of detail to the point of beening pretty unusable?

Thanks in advance

Hi kiwi_ferg,

Welcome to the Raymarine forum

Please attach a photo of your issue for us to look at.

Check that you have a chart card inserted in the unit and the correct type of chart selected - ei C-Map or Navionics. No chart card in the unit will certainly give those sort of issues.

Kind regards
Jules
