It allows automatic reset after impact. Also includes a latch to catch spray arm if shear bolt breaks. Email is an option as well but I didn’t do it so can’t comment on it. Good updates for old workhorse in a small town market.
You can get a refurbished A5000 from RDM for $425 (you have to return your old controller). Call and find out what software version is in it, but if memory serves me correctly, it should be version 20. That should give you the auto adjust around mirrors and trailer hitches.
Just know that there is a bug in version 20 where your bay temp may read incorrectly. The temp will get stuck occasionally.
