I learned this from the other thread and upgraded the firmware for DAB202. It is working great!@TSN
Turns out you can use the same firmware for the DAB205 that is in the DAB201 and 202. I just got some in stock and I am installing the DAB202 firmware in them now. Not sure why I was originally told that you could not, but I'm now told you can. I think that they would rather it say DAB205 in the firmware section of the menu instead of DAB201 or DAB202. I need the speed in MPH, so DAB202 firmware it is. Stock firmware for the 205 was km/h only.
