This downgrade worked perfectly for me also. I went from version 70MT back to 40M because the POI were never showing up in 70. Now they work great in 40 again. I just had to remember that when the instructions said (BACK) I was supposed to push the BAND button. When the instructions said to go to TEST MODE Page One, I was supposed to use the JoyPad Left.
Now that I have downloaded version 80MT, I am going to try the same steps and see if I can get that to work .
Thanks for the instructions!!
