Swing Radio (Mk3/6V0035869D) Powering on/off

The radio in my 2018 Fabia is acting up it keeps turning itself on and off (when its off the display goes blank) although when it comes back on its still at the same radio station etc it was tuned to when it stopped. If I drive with the radio turned of the clock display comes and goes but it doesn't loose time/revert to 12:00 

Sometimes (not always) when it comes back on I get the message "Component Protection Active" Also the issue seems to be temperature related. i.e. when powered on from cold will work for maybe 15-30 minutes before it starts powering up and down with increasing frequency.

Tried disconnecting the battery overnight (to rule out firmware issues) and factory reset to no avail.

I've tried looking for replacements online to little avail. No new units seem to be available and second hand units are fairly expensive for what they are.

I've considered aftermarket (double DIN) replacements but am worried about loosing functionality of the "car" button like Green score, TPMS, time to next service, and especially the rear parking radar sensor. 

Are there any replacement options which don't involve sacrificing this functionality ? Alternatively are Skoda branded replacement options available for a reasonable price ?
