The biggest concern if I connect my phone via AUX is I cannot do NEXT/PREVIOUS while driving.

So got this BLUEDIO AV 890. This connects to my phone and has buttons for NEXT/PREVIOUS so now there is no need for me to look at the phone if I want to skip a song.

Simply loving it. But I cannot charge this in my car as it comes with only wall charger. Once charged I can use it for at least 3-4 days with 1 hr/day usage.
Post some pics of the device in usage, if possible, a videos would be better.

thank you. can you throw some light into the schematics? or provide any detailed diagrams etc?
Dear Aravind, why don't you drop a PM to Saroya? I am sure he would be able to share whatever he has done to install the USB port in his Alto.

I haven't read all posts in this thread. Not sure if some has suggested this.

A simple (and cheapest) way to enable USB play on a non USB HU is to get a FM transmitter with USB/AUX/SD card slots and connect it to the Car 12v charger. Configure the FM frequency and play your favo music from USB drive.

One example for reference :
CAR Audio 5 IN 1 CAR MP3 Player AD915 FM Modulator FM Transmitter SD MMC USB | eBay
