You're welcome!Thanks for bringing to our attention.
After going through it they need to add a second USB and an SD card slot since the NAV is already using up the existing SD slot.
I prefer my music to be stored on SD because it will Index faster.
With the way it is now if you use a thumb drive for music you lose the luxury of only requiring the USB portion of a phone charger cord in the car while music is being played with a thumb drive.
If power is what you want to be better off with without worry, getting a phone with a removable battery is always a good route to go, like a Samsung Note. Either get multiple OEM batteries or a big aftermarket batteryI see. I ordered extra 12v outlets so I can use the one in front to charge my Phone when needed. But my current BlackBerry can last almost two days on a single charge, and I almost never have to charge it en route.
And, I am thinking about buyong an Ipod to stream my music, including Spotify.
