Thread: How to change the Nuvi 37xx splash screen (startup/USB logo)

@Gungasur
The basic method for modding 16.bin using GIR_Editor is explained in this thread's initial post about nuvi 37xx. The same basic procedure is used regardless of the Garmin model, provided the original file type and picture size is respected with regard to the replacement image (e.g. in aera 500 it's BMP format, 480x212x16 Pixels) then you can put anything you like in either the first or second image of the BIN file:

You can have two different images display on your aera splash screen if you want, one during the first stage of boot up and another in the second stage.

The initial post explains how to flash region 16 using RGN_Tool etc., however it's much easier to use the SD method as you'd now realize because that doesn't involve making RGN files and putting the device into preboot mode to flash with Updater.exe. You can learn more about making SD kits for logo flashing in the thread i linked in Post #2 above, and more generally read about SD flashing in [Only registered and activated users can see links. ]. Note that to re-use a flash kit you must first remove last_id.bin from the HWID folder (e.g. for your aera that's the 1063 folder). That bin file is created when the flash is initiated and then if it's present later a subsequent flash won't be initiated by the device.
