OK, I need volunteers! I think I have an easy way to install the ShortFuse hack with no TestMode, editing or patching involved. I've tested as much as I can on my unit. So I'm releasing here for you guys. Maybe some of the more experienced guys try it first to increase confidence before noobs start using it.
Just download this attached zip, unzip, and copy the 3 files to the root of a blank fat32 formatted SD. When you insert it into your AVIC it runs a script that will backup both your existing RenewalIFLib.dll files, then overwrite them with a pre-hacked one. If, for some reason, this doesn't allow installing the 2017 maps on your unit, the backup files could be manually re-installed. But that isn't really necessary. So it should do no permanent harm if it doesn't work. However, I have high confidence it will.
Note: this zip has a special Testmode.key that should only be used to run scripts. It isn't the supertestmode version that allows running the maintenance menu. Also, to prevent over-writing your backed-up original RenewalIFLib.dll files on the SD, the script deletes TestMode.key on the SD. So if you insert it again, nothing will happen. It can only be run again with manual intervention. Don't try rerunning it unless you know what you are doing. Overwriting your original RenewalIFLib.dll files on the SD isn't necessarily a huge problem, but it might make recovery (in the unlikely event it is necessary) a little more difficult.
When you insert the SD, it will prompt you to press any key (button) to continue - or - turn off the ignition to abort. If you decide to abort, just turn off and on your unit - then eject the SD. Nothing on your unit will have changed. But in order to re-run, you'll need to re-build the SD from the zipped files (since Testmode.key has been deleted off the SD).
Otherwise, it will copy your original RenewalIFLib.dll files from USER/PRG0/APL and PRG1/APL onto the SD and rename them RenewalIFLib.dl0 and RenewalIFLib.dl1, Then it will copy the pre-hacked RenewalIFLib.dll in their place on the AVIC.
So.... any volunteers???? Be sure to post your results. If it goes as smoothly as I expect, I'll update the instructions in post #1. Remember, this script will not affect the operation of your unit in any way. It just prepares it to make installation of the map update easier.
Oh yeah, you'll still need to download and run the map update and enter a dummy password when asked for the Pioneer one. This should work for the US and EU maps.
