I don't think you misunderstood Giomen, even if ldr.bin was in 1371 folder the reg_140.bin is in the wrong place. Which is why it didn't work to flash his reg_140.bin of course.

If you do want to get rid of the BT icon and get your 2445 back to how it was, firstly ensure your 2445 is running V8.20 firware, update it if necessary. Then do this:

1. Open a copy your reg_140.bin with Mod_3xxx.exe and check/uncheck as below:

[Only registered and activated users can see links. ] [or check how you want it but definitely don't check ecoRoute HD, ecoRoute Purchase, Bluetooth or ASR].

2. Extract this file directly to a clean microSD: [Only registered and activated users can see links. ] and then place your modded reg_140.bin in the root of the microSD [that means to place it with, not in, the Garmin folder].

3. Ensure the device is fully off then insert the card and turn it on. You should see 'Loader' appear on the screen. Let it finish flashing, it will then boot and the useless BT icon should be gone. You'll also have a backup of your current rgn140 in the root of the card as bup_140.bin.

In Garmin.rar file is Garmin\Updater\1371. Inside 1371 is V8.20 ldr.bin and Update.txt with
rrgn,140,1:/bup_140.bin
xrgn,140,1:/reg_140.bin
reboot
