ciao,
Marc
I picked up a 16GB sd card this morning. I will mess with it tonight.
did the software update. Touch does still not work. its a loss at this point.
I don’t know how much longer you want to fool with this, but I offer the following as a next step if you want to pursue it:
The pic below shows how I isolate switch problems from software problems. I have a 12 volt WIFI Router hooked to the Ethernet port on the MFD and take control with my iPad using the Lowrance Link APP. The router has the same functionality as the Lowrance GoFree module but much cheaper.
you can see that my HDS Gen3 is at the accept screen and when I touched the accept button on my iPad, it moved on to the Home Screen. If this works the same for yours you could move on and recalibrate the screen (if it will recalibrate).
If you want to try this, you could borrow a Lowrance GoFree module or I can loan you my homemade version.
Not trying to push but will help as needed.
I try to drive as if my 16 year old Grandson is following me
