Hi HaroldZen and welcome to the Ford SYNC Forum. Unfortunately, no...SYNC 3.0 can not be factory upgraded to SYNC 3.4, and will not be factory upgrade-able in the future. Good luck.

Hi dsanfili. No, it will not reset the NAV maps version. It will be retained. Same with the SYNC 3 system version etc. You will probably need to reconnect your phone to your vehicle, reset favorite stations etc. The Owners Manual also explains how to perform a Master Reset, what it actually does, etc. If you do not have your hard copy, you can download the PDF version here: https://www.fleet.ford.com/parts-service/resources/owner-manuals/ Let us know how you make out and good luck.

Hi Ozbob. Here is the link to the SYNC 3 NAV map updated website: https://syncnavigation.com/lincoln/home Let us know how you make out and good luck.

Hi geterdone and welcome to the Ford SYNC Forum. It looks as though your 2008 Edge is not equipped with SYNC. It was an optional feature back then, and yours does not seem to even have the small SYNC display, let alone the full NAV screen/SYNC display. Out of curiosity...Does your 2008 Edge even have a USB port? Good luck.

Hi misterg. As advised in your other thread, first perform any available/recommend system updates to see if they correct the issue. Once you do that, post back with the results. You can try disconnecting the battery if you wish. Although I do not normally like to recommend that as a fix-all, it is worth a try if you want to try and avoid the cost of a Dealer visit. Keep us updated and good luck.

Hi misterg. Perform any available/recommended system updates. Good luck.

Hi Ajmal. Then my only thought would be to ensure any setting that offers an automatic time/date update is enabled. Otherwise, unless another member has some insight into this issue, you will probably need a Ford Dealer to adjust this for you, or diagnose any problem causing the incorrect date to display. Let us know how you make out and good luck. .

Hi Ajmal. Yes, you mentioned in your first post that it is an Explorer XLT. But again, you still have not stated what model year, and settings/procedures can sometimes vary from one model year to the next. Unless someone else here can jump in with the correct procedure, it would be quicker for you to find the answer in the SYNC section of your Owners Manual. Or if you do not have your hard copy, you can download the PDF version from the website I previously linked to and research it there. Keep us updated and good luck.

Hi Ajmal and welcome to the Ford SYNC Forum. I am not sure what you are referring to by the "wrong date". Also, you do not mention which model year your vehicle is. If whatever you need to adjust is owner adjustable, it will be covered in the Owners Manual. If you do not have your hard copy, you can download the PDF version here: https://www.fleet.ford.com/parts-service/resources/owner-manuals/ Let us know how you make out and good luck.

Wishing everyone a healthy, safe, prosperous and Happy New Year! Good luck.

Hi bnewt. Lincoln/Ford always recommend fully updating SYNC first, then performing the NAV maps update. And in some cases, it is absolutely mandatory to update SYNC first. So that is what I would recommend. 😉 Let us know how you make out and good luck.

Hi Agreer and welcome to the Ford SYNC Forum. Assuming we are discussing SYNC 3.4 updating? Ford does not normally issue any sort of detailed release notes with SYNC updates. The extent of what will normally be stated is some version of...(paraphrasing)..."To enhance the SYNC 3 experience, this update contains bug fixes and/or compatibility updates for new iOS and Droid operating systems." There is a compiled list of updates somewhere that I have seen, but it simply consists of the update numbers, no specific information as to what each update actually contains or addresses. The latest update always rolls up all previous updates, so all we need to do...or basically can do as owners, is check for updates on the appropriate Ford or Lincoln SYNC 3 update website. Ford: https://www.ford.com/support/sync-maps-updates/ Lincoln: https://www.lincoln.com/support/sync-maps-updates/ On a related note for us gear-heads and software geeks: With the release of SYNC 4 and the soon to be released Google based system, SYNC 3.0/3.4 are now legacy systems. SYNC 3.0/3.4 updates do not include or introduce new features. As mentioned above, the updates simply consist of bug fixes and compatibility updates for new iOS and Droid releases. So if everything is working properly in your SYNC 3 system, there is no big rush. Sort of the "If it ain't broke don't fix it" philosophy. That being said, it is still a good idea to periodically check for and install any available updates, if/when released. As an FYI: Even when the systems were new, SYNC 3.0/SYNC 3.4 updates were not and are not released anywhere near as often as often as Windows/iOS updates. It is not a weekly or monthly thing. So while you can check as often as you like, there will rarely be an SYNC 3 update available. So a good rule of thumb (to save our sanity) is check once a month or two months. For example, there has not been a SYNC 3.0 update for my 2018 MKZ in ~2 years. So again, SYNC 3.0/3.4 updates are only released to fix bugs. On the other hand, SYNC 3.0/3.4 Navigation Map updates are released once a year. Normally around August/September. Also, keep in mind this is all referring to SYNC 3.0/3.4. SYNC 4 is an entirely different animal. Let us know how you make out and good luck.

Hi Python. If the Ford SYNC website shows you are up to date, then your current version is the latest version compatible with your vehicle. Good luck.

Hi Wiremaniac. I don't have access to my vehicle at the moment, so off memory: Try going into Settings, then look in the "About SYNC" section. Let us know how you make out and good luck.

Hi cp1084 and welcome to the Ford SYNC Forum. Concerning Bluetooth: Try disconnecting your phone and deleting the SYNC Bluetooth connection on your phone. Then reboot you phone. Then perform a SYNC Master Reset (instructions on how to do so are in your Owners Manual). Then re-pair your phone to SYNC. See if that works. If you do not have your Owners Manual hard copy, you can download the PDF version here: https://www.fleet.ford.com/parts-service/resources/owner-manuals/ Concerning Apple CarPlay: Did Apple CarPlay work in your vehicle before you performed the update? Someone will correct me if I am wrong, but I don't believe Apple CarPlay was available in early SYNC 3 versions (such as yours) and yours can not be updated for that feature. Let us know how you make out and good luck.
