I have the predecessor Solar-Dab (without the Plus), which is no longer supported since Tuesday, 15.11.16. Can this be retrofitted via a software update?
(usb input is available...)
Good day
I had exactly the same problem with the Roberts "without +" and researched for a long time, coming to the realisation that unfortunately it cannot be updated. I then decided (with a heavy heart) to buy the successor "Roberts SolarDAB 2". I don't regret this change in any way, the new one is even better in terms of solar power, batteries and charger have definitely become superfluous.
