    I think no one here is interested in that except you.
    RTL Trap means Run Time Library Trap. Run Time Library is a set of functions that deal with semaphores, dynamic memory, etc. I don't know the whole list of things.
    There is a special function that's called by runtime library when the rest of firmware does something wrong like releasing semaphore which hasn't been reserved. This function writes "RTL Trap Error" crash log somewhere and shuts the unit down.

    And I think you are probably one of the few who knows. Thank you. So can you decode what is written inside an html? For example:

    The trap function was called with error code R1=0x6E5D8022, which has no description in firmware, so the function decided to report error code 0x6E5D8004 and save original error code to R1. R0 is a current thread descriptor, which looks like just a pointer to RAM.
    I can't find 0x6E5D8022 in the firmware and this is strange, maybe it was generated like 0x6E5D8002 + 0x20.

    Default RTL Trap Nuvi 1300 Firmware 5.7

    After loading firmware 5.70 i got RTL Traps a lot.(Nuvi 1300 with Modded Splash)

    I kept upgrading via My Dashboard

    Two Small Quick Updates have been received after 5.7 (Large Update)
    Now I think the RTL traps are cured.

    This does not affect the trap.

    Can you post your RTL Traps from your nuvis 1300/1400 with FW 5.70? Is it Error Number: 6E5D800E?

    Thanks,
