3.0 is the latest firmware that is useable with KPG-111D. If you go up to the most recently released, 3.20, then you would need to update to KPG-111DN to access all the options, however KPG-111DN requires you program to narrow band analog freqencies only, so this can be an issue for Ham operators. I haven't tried it yet, but I know Kenwood has left holes in this for Ham operators, so may not be an issue.
