After numerous attempts and trials..this is what I have concluded. Hope the info helps someone!!
MFT and HDD
- USB 3 HDD doesnt work. Need USB 2. I am using a 500 GB Usb 2 HDD
- Fat 32 format
- I have over 3000 songs (about 30 GB) and it ONLY works (indexes only once!) if I copy all the songs in the root folder. I used to have them all organized in folders, but that causes MFT to continue indexing every time I switch on the vehicle. I had enough removing the fuse power! As discussed earlier, I am assuming there is a size limitation for the index file. The index file must be storing reference location for the songs and all other info. Removing the folder locations must be reducing the size of the index file.
MFT and Phones
I am an Android user and used various phones and various ROMS to see what works best. I have used some Samsung devices (SII & Note with original Samsung ROM and custom ROMS) and HTC devices (Evo 3D and Sensation XE). I have to say that both the HTC devices worked well. The following functions works well:
- Connection via bluetooth is almost immediate
- Contacts pictures works
- Messages works
- Streaming music via bluetooth
- Phone calls (and it disconnects correctly and continues playing songs)
Note that you will need to enable the messages etc option in Advanced options of the bluetooth seetings of your HTC device.
