Thread: 1490 Skin Change, noob questions

Hi, so i have an old 1490 LTM, I'd like to customize its appearance...

fully updated 2025 using garmin express.

pcb 105-01617-11 ver 7

SW ver 6.30 nuvi 1490 i KP1 V7 LC 4GB

I have been wading through old forums on the wayback machine, and found some useful tools, RGN_Editor, GIR_Editor, TTS_Voices editor etc. I have extracted the symbols/icons, from the GUPDATE.GCD file.

I thought I'd ask on here before attempting to go much further, I figured it's better to ask first how to do it, than try to fix it once it's bricked.

I've been able to access some of the hidden menus, via the battery symbol and the speedo face. However I haven't been able to put it into MSM mode. Although when plugged into a linux machine all files are accessible.

So, using the the RGN_Tool i extracted the .bin files. Then using GIR_Editor i extracted the symbols from fw1_resources.bin.

Can i just replace the images, then recompile the GUPDATE.GCD file (from the three bin files) and replace it with the original one on the nuvi?

Or do I need to force it to update.

I have also downloaded the updater.exe and the USBDrivers_2312.exe should i need them.

...think that's it, thanks
