pionara Posted October 2, 2012 Report Share Posted October 2, 2012 (edited) I have found the place to patch in Navi.exe where you can enable the "Safe Mode" switch in settings menu on US/CAN units (that EU models have). This is just for navi.exe version 4.010 on X92x+ or Z1xx series, havent figured it out yet on older versions, but could be done in a similar fashion. 1. Grab your navi.exe from your unit. (Keep a copy as a backup.) On your pc, with hex editor change: a. offset 15aefc from 02 00 56 E3 to 09 00 56 E3. b. offset 15aee8 from 01 10 A0 E3 to 00 10 A0 E3 2. replace the navi.exe on your unit. You should see a new "Safe Mode" toggle switch in the settings menu (bottom row, right side). Please dont attempt if you are not comfortable hex editing files and copy files via testmode. I wont post binaries, but somebody else can make this edit and post it somewhere on the tubes Oh you are totally on your own using this. This is only for use with US/CAN navi where the law allows. update: verified that it works. A few notes: 1. with this, you no longer need to ground KMODE (pin 11 of A/V connector) - it is not necessary 2. you will need PKB grounded so that you can turn safe mode off. Once safe mode is off, you will not need PKB pin grounded, however: 3. if you ever turn safe mode back on again, then because safe mode button along with all the other ones are greyed out, you will need to re-ground PKB to get the safe mode button active again, so you can turn it off There may be another hack somewhere to fix 2 & 3, but at least with this, you dont need to fool with the A/V connector Found it!! There are two edits. First one enables safe mode button in menu on UC units, and second one keeps the button active in safe mode.. So no wired hacks needed. 100% pure soft hack!!

pionara Posted October 8, 2012 Author Report Share Posted October 8, 2012 didnt do an actual driving test with this, so would like to hear some feedback on if this works Quote Link to post Share on other sites

Jfinley0 Posted October 9, 2012 Report Share Posted October 9, 2012 some screenshots of what it looks like... Hi There: I search for the offset 15aefc and offset 15aee8 and did not find the code in Nav.exe. Can you upload it and I will try it or maybe I don't have the right Hex changer program. Thanks Jimbo Quote Link to post Share on other sites
pionara Posted October 9, 2012 Author Report Share Posted October 9, 2012 you have navi.exe from 4.001 2012 software? Which model do you have? Quote Link to post Share on other sites
Jfinley0 Posted October 9, 2012 Report Share Posted October 9, 2012 you have navi.exe from 4.001 2012 software? Which model do you have? I have x940bt. I do have 4.001 software. I can email you the nav.exe if I get you email. Thanks Jimbo Quote Link to post Share on other sites
Alexei Navalny Posted October 9, 2012 Report Share Posted October 9, 2012 a. offset 15aefc from 02 00 56 E3 to 09 00 56 E3. b. offset 15aee8 from 01 00 A0 E3 to 00 00 A0 E3 Haven't tried patching yet, but @ 15aee8 I've got: 01 10 A0 E3 instead. The other offset is correct. I'm running Apl v4.010 on a Z110. Quote Link to post Share on other sites
pionara Posted October 10, 2012 Author Report Share Posted October 10, 2012 you are right ron, i typoed that. it should be offset 15aee8 from 01 10 A0 E3 to 00 10 A0 E3 I fixed the instructions Quote Link to post Share on other sites
Jfinley0 Posted October 10, 2012 Report Share Posted October 10, 2012 I have x940bt. I do have 4.001 software. I can email you the nav.exe if I get you email. Thanks Jimbo I have the 4.000 software. Can I upgrade to 4.001 software? Jimbo Quote Link to post Share on other sites
Alexei Navalny Posted October 10, 2012 Report Share Posted October 10, 2012 you are right ron, i typoed that. it should be offset 15aee8 from 01 10 A0 E3 to 00 10 A0 E3 I fixed the instructions OK, but I already have the harness bypassed, so I'm not going to remove the unit just to un-do that. I'll be installing the traffic tuner module in a couple weeks, so I'll try it then. It would be great if this became the defacto PB hack going forward, but then - with each upgrade the hack would have be to re-tested (by you?) and re-installed. Not a huge task, but an un-necessary hassle if you've already hacked the harness. Quote Link to post Share on other sites
pionara Posted October 10, 2012 Author Report Share Posted October 10, 2012 Yep Ron, thats the downside to any soft hack, must be redeployed after any update (or applied to update before installing). Even if you properly wire PKB according to manufacturers instructions, this can be helpful. So useful for those folks who dont want to deal with the extra KMODE pin on A/V harness.

EChavez Posted October 25, 2012 Report Share Posted October 25, 2012 Hi, I just purchased my AVIC-X940 and I'm getting around to install it. I didn't wanna do the wire bypass and I wanted to try this bypass, I have a couple questions though. 1) How would I get the Nav.exe onto my computer? Where is it located? 2) Where would I check to see what version I have? Any help would be greatly apprecited. Quote Link to post Share on other sites
pionara Posted October 25, 2012 Author Report Share Posted October 25, 2012 you would need to use testmode to get the files on and off of your computer. Read some of the other threads about testmode. be careful, take backups before you mod anything. I think there is a youtube video of navigating testmode. version info is under settings, system settings, service information. You probably have 4.010, which is the version i give instructions for.

random1 Posted November 16, 2012 Report Share Posted November 16, 2012 If one edits the navi.exe file before doing the upgrade to z140, would that work? It'd be easier for me, then I don't have to worry about testmode, just the edit. Quote Link to post Share on other sites
