I have a couple of Roger ON iN’s which have been updated with the latest firmware and have Roger licenses. I have tested them and all functions work correctly except for the display. The displays are inoperative so they need to be paired with the myRogerMic apps. The myRogerMic app essentially duplicates the display on the Roger. If you are like most, you will not pay any attention to the display once you become familiar with the Roger. I am asking $75 plus postage. This is a hobby and I just try to break even, not for profit 
If anyone is interested I will be happy to send one to you so you can try it. If you decide it works for you you can send payment. If it doesn’t just send it back to me. If you have any questions, please message me.
Addendum to the above post. I had five of these Roger On iN’s but apparently there was no interest in trying them. I was asking $75 (my cost) but will give them away for the postage if someone really wants to try a Roger On iN. I had five which I bought on Ebay for “parts” but as noted above they all worked perfectly except for the display. I have given away three to forum members and have two left. If somebody wants one, message me.
