AVIC-F30/40BT v5 running 2013 maps and update.

Has anyone managed to remove the warning text from the back up camera display?

I've tried modifying the EUGBENG.LNG & UCUSENU.LNG files by replacing the text with spaces but having replaced the files on the unit the camera output still displays the text.

I used this X Series thread as guidance

Any help much appreciated…

Edit

So the key to this is in the wording of the linked thread… each language file has 2 instances of the text to be removed… simple once I'd re-read the original thread a few times, just annoyed I'd missed it the first time, hope this helps anyone else trying to do this.
