I am afraid that you are out of luck on that one, mate... not likely to be compatible like the d/s.
The "freezing" that you are encountering is very common with those instruments... some sort of software
glitch (that they deny ever happens). But, all it takes to recover is a momentary interruption of the 12 volt supply to the instrument head
. If you want easy access to this operation, you could put a small toggle or pushbutton switch on your instrumnet panel to cycle the power off and back on. A small PITA...
