just installed my DCI and im very satisfied. but 1 question my volume is kind of laggy when i press up or down rapidly. is this normal for everyone else? i have the wired DCI on a Alpine 9855. any feedback is appreciated thank you!

 

I haven't researched sound systems since I had my 03' S2000, but from what I recall, this is normal.

 

I have the IR version and there is a slight delay, I assume it is from the DCI making the command and sending the IR signal.
