I recently bought a Dice R4 for my Acura TL-S '07 and an Ipod touch. Everything went fine in the installation and text displays but sound isn't right. It doesn't have any bass and the sound comes lower than it has to be. The thing is that when you change the PRESET or hit any button it starts sounding good but after 1sec it goes back to how it was sounding. I disconnected the dice cable and went to use the 1/8 on the jack of the car and it works very good, with the sound rich and everything. Please help.
