Hey am I the only one who finds the beep-beep horn on the ML annoying? has anyone ever changed them to more of a truck horn than one I had on a scooter? Any idea how many there are and where to locate them?

Horn upgrade is an easy plug and play on the ML. You can see them through the wheel wells on either side. I replaced mine with the ML 55 horns. A lot louder and sound more like a Mercedes. Some have opted to upgrade to air horns which are really loud. Just depends on personal choice as to what sound you want. My 2 cents.

I think the ML320 horn is fine, and I don't really consider it a "truck" anyway.
It is an SUV and the horn is almost like the 60's Mercedes horns -- which had a much better sound than the typical American car. What do you want to do, scare people out of the way or attract attention?? (just kidding)

Make sure BOTH are working. 1 horn definitely sounds insufficient. 2 really isn't that bad.

Put a single or a pair of Stebel Nautilus, at 139dB, your horn will sound macho enough
