Have a 2006 e4 gem now using for hunting
does anyone know how to disable reverse horn

I found this using the search function. It should answer your question - http://www.electricforum.com/cars/neighborhood-electric-vehicles-hev/4687-gem-2008-backup-beeper.html

Does anyone know how to disable backup for 2005 e2?

This may help…
Not sure of years it covers…

Got my whole dash apart…
Still can’t find it…
