So I am between a rock and hard place.. Either get a note 4 edge or iphone 6+ or wait for the 6s+ (hear they might release one in june.) but thats beside the fact/point.. But on my galaxy s4 I have viper4android fx audio mod and it works great really (for ex.. my other car a 10 cadi dts base model its ok with it off but I turn the mod on she sounds great) if I switch I know I will lose it. So I am trying to find apps that can replace it on ios. (Phone will go for a week without being jailbroken Btw) I do realize that ios allows you to dock which an audio mod app may be useless but mostly I run aux cable. Lack of radios that are dock-able at this time. thanks hoping yall can help me out. Google can't help me..
