s1ujhe Posted May 31, 2023 Report Share Posted May 31, 2023 I know about holding 3 and 6 for a basic test mode. Tho i remember from years ago there was another Debug mode of some kind that had a couple additional features. It had a sequence - getting into address book, entering a certain name, then hitting a hidden button somewhere - or something like that. Does anyone have anything on that? I know these units are old and could be easily upgraded, but we have two 2007 GT500s that are identical - his/hers - and we're keeping the original units. One unit had gone bad - and we had to replace with a Ford Edge unit, so it doesn't have the 'convertible' DSP setting - it has a 'rear' instead - so I was looking to see if I could modify that setting. Any input would be great. Thanks! Quote Link to post Share on other sites
s1ujhe Posted June 1, 2023 Author Report Share Posted June 1, 2023 Found my own answer in an old post on another site... 1. Take vehicle outside and agree to nav instructions. The gps needs to know its position. 2. Push hard nav button (on right side of radio). Go to your address book. Pick any of one of your saved addresses. Now that address is highlighted, look to right and push soft edit button. You will now see name of saved address. 3. Clear name of saved address and type in F-DEVELOP ON (make sure to put space between DEVELOP and ON). 4. Now look to the upper left corner and you will see the word ADDRESS. Place your finger directly under the A and hold. If you do this right, the screen should change to the map screen. 5. Now push your hard menu button (on left side of radio). Across top of radio push soft SECURITY button. You have now entered security screen. You will see nothing in the right most corner of nav screen. Push your finger and hold in that position till the screen changes. 6. You now have entered a parameter screen. Locate DRIVING RESTRICTIONS release. When you push the button it should change to driving restrictions stop. Exit the screen by pushing the soft BACK button. 7. Congrats you have just programmed your factory nav radio. NOTE: Every time you turn your vehicle off, you will need to repeat steps 5 & 6. Quote Link to post Share on other sites
