Yes I did. Unfortunately, even with the speaker volume turned up to max, I don't think the alert would be loud enough if I have music on at a moderate volume. I then tried to aim the speaker out through one of the openings, but then the cover wouldn't fit back on correctly, so i decided to leave it on the outside. I'm sure if I tried a few more positions I could have hidden it, but you can't see anything at all where it is unless you stick your head under the steering wheel.
