I am considering buying a 2 year old E-Trac from a friend and wanted to see if there were any differences between the newest E-Trac units coming out today VS older ones. Next question would be, can I upgrade the E-Trac firmware in the field or would it need to be sent in (assuming there have been updates in 2 years)?
Thanks in advance,
