I was hoping someone could provide a list of specific model numbers that support the upgrade. I like to buy spare validators off of eBay or CL and get them cleaned up and upgraded.
I have several FSI machines that came with some stops I bought. I was ready to replace them, but they've performed adequately and have given me no problems. Here's my question: I am currently installing remote monitoring equipment to my route. Is there anyway to collect DEX data from models 3120 & 3130?
