With Apple car play the music app and podcasting apps give you full control pretty much of everything that you can do with your phone save for searching..Interesting idea. Phones tend to have a lot of sound settings that change highs and lows as a normal setting without equalisation. I might try this out of curiosity, however, I find it hard to run the music from my phone without using some app through Android auto. I'd rather have full control using Honda's built in system and I've had trouble in the past doing this. I will look further into it. Another caveat is I'm running about 500 watts and I have the center channel which makes a tremendous amount of difference in sound. Honda's DSP seems intent on pushing all voice and as much highs it can into that center making it blare like a banshee in heat. I listened to an ex model and it was way less intrusive without the dang center channel but much less detailed considering the tweeters were different. I'm hoping the new speakers with sound dampening will help this problem. If not, I can slave off the amp with an audio control unit and maybe sum the center into the left right front speakers using a new amp. The only problem I might run into is the fact the GPS and voice control run through this speaker and by summing it the music volume may not drop enough when the GPS speaks. Sheesh. What a pain.
Final note. You should complain to Honda about your dealer. They sold you a new car with rattles in it. They should darn well fix it!
I'm kinda hurt that you think the EX sound system doesn't sound good though lol.. I think it sounds great for a stock sound system. I even drove the Accord with the same 10 speaker system with the center channel and honestly besides being louder, I thought it sounded horrible.. It broke up badly when you did play it loud and like you were saying - they were trying to do too much with the DSP..
