Which radar do you have? I recently upgraded my e120 to an axiom+. While it was a royal pain, I was able to keep my digital HD array functional with some critical
software updates to enable it to communicate with the new axiom.
The key is that the old radar must be digital in order for the axiom to be able to talk with it. The e120 could
work with either the analog or digital radars, so you’ll have to check to see which radar type you have.
