Title: Lags, skips, do NOT recommend
Review: Just returned this item as it works pretty badly. Instruction is not very straightforward but OK, programming OK.The biggest concern is that you need to hold button for at least 2 sec, otherwise button is not recognized. BUT, once you hold for a little bit longer (say 2.2 sec) it will send two or more commands in a row, which means you would skip more than one track or mute and immediately unmute. I would by metra device instead
