At first we were thinking that Maxidiag series was a updatable product but you have to pay for the update fee. Then we found out there are some hardware restrictions to this series, so we develop a new model, Maxidiag Elite. We have changed the whole software structure for this new model, so it is impossible to move the software to the old Maxidiag series. Considering the high cost for a update annual fee, I think it is a more popolar idea to purchase a new model, which just costs 100 more.
