    He concludes by saying:If you have a HWID other than 0834 you can load your fw_all.bin file into a disassembler and look for similar code that most likely is at a different offset.
    Sorry, I was being rhetorical (or you might say, a smart-ass) as i know you can't disable it by an edit.

    Done, as discussed and agreed with catymag.

    Yes, best left to Loly and company imo. I'm not game to play with any of my 3xxx units to that extent either.

    If anyone still is interested in disabling the warning message on 3xxx, please try the following patch to the fw_all.bin for HWID 1101, version 5.00:

    In fw_all.bin at file offset 0x26AA02 patch from 00 F0 66 FA to C0 46 C0 46. I'm pretty sure that will get it. If you need for another HWID or SW ver, just let me know and I'll see what I can do.

    I just realized that I may have found the patch for a different HWID than the OP. Let me see if I can find the GCD for the correct HWID.

    To disable the startup and wake from sleep WARNING screen apply the following patches to the version 8.20 of the HWID 1376 firmware

    At file offset 0x1F104E patch from 20 F0 44 FE to C0 46 C0 46
    At file offset 0x2109F0 patch from 01 F0 73 F9 to C0 46 C0 46

    I don't have this device or the device for the patch in my previous post above so please try these patches to verify they work and report back here.

    moddie, you're NOP-ing the calls to the function which references "STR_WARNING" string, right?
    In this case I bet that it will not work (it will crash the firmware).

    Correct, I am NOP-ing them. The same method worked on my 2x5W so I figured it may work for this one as well. Nice thing about these is that even if it doesn't work, it will not brick the device.

    On the 1101 firmware, I had thought about NOP-ing out the call to sub_802EA9AC which displays the EULA or the WARNING but figured disabling the EULA might not be necessary since it only displays once per hard reset instead of every boot.

    I agree that the test is 100% safe so (once the user learns entering pre-boot mode) let's see if I'm right
    If I were you, I would prepare two firmwares in RGN format: original one and patched one.

    My personal preference is to reserve RGN preparation for emergencies. I guess you could say I'm a GCD man. I'm just too lazy to put my device into pre-boot mode unless I have to.

    In case anyone needs step-by-step instructions...
    Here is how to apply the patch:
    • Get a copy of the version 8.20 firmware for HWID 1376.
    • Open the firmware (either .GCD or .RGN file) in TurboCCC's RGN_Tool
      Code:
      Please Login or Register to see the links
    • Click the "Save..." button in the fw_all.bin section and save the fw_all.bin file.
    • Open the fw_all.bin file in your favorite hex editor
      Code:
      Please Login or Register to see the links
    • Navigate to file offset 0x1F104E and change 20 F0 44 FE to C0 46 C0 46
    • Navigate to file offset 0x2109F0 and change 01 F0 73 F9 to C0 46 C0 46
    • Close your hex editor and save the modified fw_all.bin file
    • Click the "Load..." button in the fw_all.bin section and load the modified fw_all.bin file.
    • Click the SW Version box in the Overrides section of RGN_Tool and change the value to 821 (or a value higher than the current SW Version listed in the fw_all.bin section) so your device will upgrade to your patched firmware. (This step is not necessary if you prefer to save as an RGN file and use pre-boot method)
    • Click on the GCD button in RGN_Tool and save the GUPDATE.GCD file to the Garmin folder of your nuvi
    • Finally, safely remove your nuvi and power it up and wait for the firmware upgrade to take place and the device to boot and you're done.

    If you play with fw_all.bin you need to calculate checksum before you pack it back in gcd.
    If you wish, you can [Only registered and activated users can see links. ]

    Which is why I use RGN_Tool because it automatically handles the checksum.
