OK. It needs to start with 089K44 or 089K45, or it's not going to work with that radio.
The 089 is the software model, KPG-89, which is for that model radio.
The K is the US market code. That has to match the radio. Your radio is a K2 version. If you were using an "E" serial number, that's going to tell the software that it's in the European market, and it won't work with the "K" radio.
Ideally you want the "44" number. That's the standard software. The "45" is the engineering software. It'll do what you want, but there's some options in that software that shouldn't be used without having some deep understanding of what they do.
