TAKE CARE !
Updating your radio is very easy, but... you can damage or brick your radio if you do not follow the procedures as noted on the Icom Firmware page.
The writer nor Famparc take any responsibility.. if you are not confident, do not do it.
Click Here for the Icom IC-705 Firmware page... Take note of all instructions etc..
Check that the link above is correct for your radio!
I updated my IC-705 which took around 5 mins.
Thanks to Phillip VK3LRO for this information and notifying me.

Hi
for those people who use the CS-705 to programme channels etc on their IC-705, and have updated the firmware on the IC-705, you will need to update the CS-705 software so that it can handshake with the update IC-705.
The CS-705 software upgrades from V1.21 to V1.30. The download link is:

Again a simple update process that is well documented, but if you have any queries, just ask.
Thank you Philip for letting us know 🤓
