Once you have followed these easy steps, your new navigation system is ready to go. The process should take no longer than 20 minutes. Once you have entered your unique serial number the new maps will start to load into the navigation system. This can be found on the DVD packaging, so don’t throw it away!ħ.) Wait. The navigation system will prompt you enter in your customer I.D. Click “yes” to proceed.Ħ.) Key in the ID number from your DVD. On most Honda navigation systems, this will be a part of the dashboard, but in some older models it is found underneath the passenger seat.Ĥ.) Remove your Honda’s old disc and insert the updated one.ĥ.) Click “yes.” The navigation system’s screen will ask you if you want to install new map updates. Once your new Honda Navigation DVD arrives in the mail, you can begin the following installation process.Ģ.) Turn your Honda’s ignition on and keep it running – the navigation system should boot up automatically.ģ.) Press “eject” on the DVD tray. You need to purchase the latest version from Navteq. Honda Navigation System Updates are released annually in a DVD format. Maps are stored inside of the system as software, so will become out of date as soon as new roads and intersections are developed.īelow are instructions on how to update the maps on a standard Honda Navigation System.ġ.) Check for updates annually. Depending on where the GPS chip is housed as sometimes they reside within the antenna and not the headunit.Įdit: Bit more digging and i found this: Safety Bulletin 24 – Furuno navigation & communication equipment (incl GMDSS) - GPS week number rollover and i'm wondering if Honda use Furuno GPS units.Many Honda vehicles come with the Honda Navigation System built-in to the dashboard. Unfortunately, if the rollover issue is the problem, the GPS antenna may need replacing too. Here's hoping that Honda do release a fix for this, otherwise i think it's time to replace the headunit with something newer. And the fact that it resets to 1am everytime i turn the ignition off. What annoys me the most is there's no option to ignore the GPS time and set it manually. I am tempted to do some digging around the files on the DVD to confirm this.įor the sake of clarity, i'm on the 2018 UK maps which i think is the latest maps for our units in the UK. If this is the issue and it's logic in the software causing the issue then a bit of hacking may be able to temporarily fix this by removing the check, although say goodbye to the auto summer time then. Mine keeps resetting to 1am when i have the auto summer time option turned on and i'm in the UK so it's applying the 1 hour summer time offset (thanks to the date being in May) but then resetting it to midnight. Probably along the lines of 'If date < unit was made, set the time to 0'. As the time reported from the GPS is correct but the date isn't, my guess is there's some logic in the code on the head unit to handle certain error conditions. To check if i was correct, i had a look at the diagnostics menu and noticed the GPS data was reporting the correct time but the date was May 2002 (which is exactly 1024 weeks ago). Got a funny look from the girlfriend when driving down the motorway saying 'i bet its gone back in time by 1024 weeks'. Or there's the GPS rollover theory, this is the one i went to as soon as i seen it. There's the 32bit signed integer issue, which is the same one that broke Exchange, and is very possible. So far there seems to be two theories on whats gone wrong. I noticed this a few days ago too and did a bit of messing to try and figure this one out. That is most likely what is causing the bug in our clocks. That worked well, until when the number changed to 2201010001, which is 11 digits and cannot be represented by 32 ones and zeros. In essence, it's just a 10 digit integer that cannot be greater than 2147483647. Now, Since Microsoft, using that option, stored dates as YYMMDDhhmm on our nav systems (10 Digits), then dates in 2021 would be stored as something like 2112311234. It looks like the folks who wrote our Navi software used that option to store our dates. The largest integer that can be stored in 32 bits is 2147483647. In binary, that's a string of 32 ones and zeros. That OS can store a date as a 32 bit integer. The Honda Navigation system uses Windows CE. I got a 2010 nav model and is doing the same, i found this on the cr-v fourm as they are having the same problems, as a software engineer it makes sense why its not working, im bummed out it might not be fixed unless they start making new navigation cd’s to update it : /
