I purchased a Dragonfly 7Pro last summer. I returned it to Flir to check and see why nothing showed up on my screen that was useable when I used the downvision or sonar. GPS seems to work just fine. It was returned to me with a statement that I was using the wrong map card (even though it was the Navionics card that came with the unit). Tried it once last year and didn't notice any improvement, even though I confirmed that it was the correct card.
Went out again on Sunday to try it out again. SAme problem. My brother came with me and brought his head with him as well as a Dragonfly4 head. Both units looked like my screens- not readable or useful. Both of his units were working fine on his boat. Didn't change any settings when he hooked up to my Transducer and power.
I have pictures of the screen
