Joying RK3188 questions

Hi I have a Joying RK3188 and I'm wondering a few things before I install a custom ROM. First, if I do a custom ROM and MCU will I lose the phone mirroring? I've heard/read different opinions on this and it's a great feature that I do not really want to lose. Second, has anyone tried using it with a AT&T Mobley? Does it maintain the wifi connection? Third, does using a custom ROM allow me to set the power off time to something > 2 hours? I've read that the energy use is minor and that 24 to 48 hours should be fine without killing a battery. Finally, what's the difference between the stock MCU and the MCU with Sleep and Musik's mod?

Thanks.

HuiFei - 2 DIN Pure Android 4.4.4 RK3188 MP3 Playback Issue

So I finally pulled the trigger and bought my HuiFei head unit. I installed it just fine and most things seem to be working ok. I keep running into a specific issue with the MicroSD card and music playback however.

It will either play fine for a few moments then hang and crash the music app, or it will randomly start playing several seconds of each song just like if you were doing a scan for radio stations. I've tried the built in music player as well as PowerAmp and have the same problem with both. I tried the format trick recommended in the main thread posted by R4D3N. That doesn't seem to have corrected the issue.

I'm using a Samsung 64GB Class 10 UHS-1 MicroSD card I bought at Best Buy (Model: MB-MP64DA/BBY). I have my MP3's sorted as follows:

\ARTIST\ALBUM\Track # - Track Title

I'm wondering if the file names are too long or if there's some other issue I'm unfamiliar with that could be causing this problem. Any advice would be appreciated.
