Sorry to dig up an old thread. I'm having this issue on my CTR. It's got sat nav. I can't get the clock to adjust to the correct time through the main unit. It seems to have gone wrong since changing both headlight bulbs and having removed the battery.
Any new fixes ideas on how to solve this.....ill give the battery disconnect a go

It's something to do with 2022 apparently some sort of bug, won't be fixed untill at least August supposedly.
This is what I've had to do as a temp fix 馃槴

Any update on this??

My alternator recently went. After being fixed, the clock just cannot go back to normal. Tried everything in settings etc but the time will not budge.

Fuse? Doubt a battery disconnect will do much?

Honda UK are aware. This is their latest response :

We have just received some more information regarding this and were advised that the Honda technical department are currently working on this.

Once there is a fix for this issue Honda authorized dealers will be made aware of it and will be able to assist with this at that point.

A service bulletin will be issued to our dealers from Honda UK on how to fix this.

As such it would be best to check with your local Honda authorized dealer for any updates as they would have the latest information for this and will be able to assist once the fix is released.

They can also contact the Honda technical department for additional assistance with this if necessary.

Hi,

I disconnected the battery on my 06 diesel Civic, something I鈥檝e done lots of times with no problem. But after reconnection, my clock was showing the time +4 hours, so 8am was 12pm.

Checked the manual and it says the time is set by the Sat Nav GPS signal. There鈥檚 a clock adjustment setting in the Sat Nav menu but it makes no difference.

I disconnected the battery for a while today in the hope it鈥檇 solve it, but now it鈥榮 showing 1am when it鈥檚 4pm.

No idea where to start so I鈥檓 hoping someone has come across this before and knows the magic to do?

Thanks

This is a problem with all of the sat Nav versions now, Honda are apprantly trying to come up with a fix but that won't be until at least August.
This is what I'm doing untill it's fixed. Or you can disconnect/reconnect the battery at 1am.

I've also had this issue, and have implemented the "hardware fix" as described by DogP over on the Acura forum (Navi clock/ dash clock Sync MEGATHREAD (UPDATE:04-06 fixed!) - AcuraZine - Acura Enthusiast Community - waiting for the admins on their forum to let me in to thank him!).

I've made a GitHub page with some more info: GitHub - dsclee1/HondaSatNavClockFix: Hardware Fix for Honda Sat Navs with GN-80 Furuno GPS modules displaying the incorrect time

For anyone not interested in the hardware fix and happy to wait until August, it looks like around 17th August 2022 is the magic date that the clock will become adjustable again - but you'll probably need auto daylight savings turned off and to adjust it manually every 6 months.

Here is a fix for owners of the West Europe White Disc 3.C0.

* Disclaimer *

I've installed this on my Sat Nav, but haven't fully tested that the clock works again. I currently have the hardmod installed, and to uninstall it would involve stripping out the dash and glove box to remove it, which I currently don't have the time to do. I'm pretty sure this should work, and I can verify that it didn't break my Sat Nav. However, do this at your own risk!

If you're the first one to try this and it works... congratulations, you're a pioneer!

What does it do?
For some reason Honda decided that 2003-01-01 is the beginning of time, and currently the Sat Nav clock is receiving times in 2002 (due to the GN-80 GPS module believing it's 2002 due to GPS week rollover). This patch changes Honda's beginning of time to 2002-01-01, which should mean the clock works again. - Well mostly, it won't adjust for DST as it will still think we're in a different month of the year.

Instructions
This will work with a CD-R/CD-RW/DVD-R/DVD-RW, personally I opted for the DVD-RW.
Copy the following files to a folder on your PC from the original Honda DVD:
A0000_00.MNG
PRG_INFO.MNG
UPDATE_APL.exe
UPDATE_APL_AVN_EU.exe
SMGA.bin
SMGA2.bin

Save "civicclock.txt" from the attachment as "civicclock.exe" in the same folder.
Run "civicclock.exe" - the SMGA.bin will be updated (check the timestamp has changed).
Delete "civicclock.exe".
Burn all the remaining files to a CD/DVD (on Windows make sure to use the "standard" mode and not the newer "USB like" mode).
Insert the new disc into the Sat Nav DVD drive. When you see the message about "Can't read disc" simultaneously hold down "Menu", "Map" and "Back" (the bottom left button that looks like an arrow looping back on itself).
On the diagnostic screen go to "Version".
Press the "Download" button, and wait until the disc is installed.
Once the system reboots you can remove the disc and put your original disc back in - and hopefully have a working dash clock!

Thank you for the instructions! For me it worked, on the dashboard, it shows the correct time now, in the diagnostic menu GPS time is still 2002, but doesn't affect me.
