HU-850 Illumination and AUM software reload???

Post by pdr1966sc » Sun Jan 06, 2019 6:35 pm

This car is 'new' to me so I do not know if this HU-850 is original or a replacment - it operates fine but the button/controls illumination is not present.
I have read that this MIGHT be resolved by an AUM software reload (possibly due to the radio having been replaced???)
The steering wheel controls work the radio fine as well.
I have Vida, but it appears on forums that we cannot do software loads from 2014D vida (- lets call this the hobby version of vida)......
Has anyone tried this? -kind of cold to stand outside doing up here this time of year - would like to resolve.

My car is suffering from this. The dial lights up, but the controls and buttons do not.
