Honda CRV Radio Alpine BB717AA, wrong time display

[Aheld]

Hi forum,
my Honda CRV Radio, Typ Alpine BB717AA, has a defect in the time generation.

After each switching on, it shows a time of "2:00"
It seems, that the clock isn't able to synchronize with GPS and also not remembering any time area settings.

Upfront of any dismounting activities, I would aks this forum is any body can support with a kind of service manual or schematics of this Alpine BB717AA radio?

My current suggestions regarding this issue are (because of the age of this device):
- defect battery for memory circuit
- defect of real time clock IC
- issues of solder connections

Other ideas are warmly welcome :-)

Thanks
Axel

Possibly due to this recent issue?

Alpine does not release schematics or service manuals on OEM equipment. Looks like jceev nailed it. you have to wait for Honda to correct it in UK? Maybe because of their laws about release of information.

Hello jceev and Jeff eelcr,

this fits exactly to this issue. Thank you for your replies.
I still remember the panic and preparation regarding new year 1999/2000 and nothing was happened.
Now for 2021/2022 Microsoft has a big bug in they eMail service and car radios are not able to process this changes?
What else in future?

Thank you for helping, I'll contact Honda for bug fixing.
