oops on my part. i will try it after work. so far the functionality and sound is great. it's the first HU that flush covers the edge of the HU unlike my previous sony one. it was showing ugly metal bracket in the edge through that i thought it was ugly and i used blue bezel accent tape to cover the tacky looks.(aka non-oem look) i end up putting the switch on empty gauge pod and it looked ok. i tried my best to look flushed. i will post some pics later how i done it.
