Full Charge or trickle?

Is there any way to see if the unit is being fast or slow charged? It seems that the HTC charger uses an extra pin on the charger to enable fast charging and that MAY be why some aftermarket chargers (wall and car) do not seem to keep up with the battery discharge when running even if their plugged into a charger with sufficiant current capability. The HTC Wall caheger is rated as a 1 Amp charger. I have other chargers that use an external USB cable to connect, both rated as 1.5Amp (1500mA) chargers but seem to charge very slow. Soooooo I'm looking for the difference between the HTC charger and the aftemarket ones to see if I can make the ones I have work properly.
Thanks for any help

<edit> in Looking at the Mini USB spec I find 5 pins labeled 1-2-3-x-4 with 1being VCC (5v), 2 & 3 being Data + & - and 4 being Gnd. Does the Advantage use the X pin to enable fast charging? How? Does it provide a second 5v line to cause/enable the Advantage to fastcharge? I think I need to look at the wall charger mini USB pinouts.

After talking to Pocket PC Techs and looking around online, it looks like the x-pin (next to pin 4(gnd)) is shorted to pin 4 to provide the advantage with a sense line to tell it to fast charge. The also shuts off the data lines in the unit AFAICT. Still don't know what the current capability of "Fast Charge" is or how to ask the unit to query the port for status. USB ports are generaly limited to 500ma and the stock charger is 1000ma (1A) so it seems that to ensure the MAX charge, the cable connected needs to have the x pin and pin 4 shorted. This is usefull if you are NOT wanting to do a data transfer (car GPS, stand alone charging, etc).
Here is a link to the connector http://pinouts.ru/PDA/pda_miniusb_pinout.shtml
Anyone can add to this?

I just received the Lil Sync DUO Mini-5 Adapter from PPC tech and it works perfectly. I'm now getting a fast charge from my PC (no sync) and I'm able to charge my S705 bluetooth headset.

Interesting news on the pinouts. I've never heard of any utility that shows fast vs. slow charge.

I wonder if anyone has a utility that can sense a gnd on the x pin (next to gnd) of the input connector. Does anyone have a schematic of the advantage side of the input power/data connector. It would me that there might be a pullup on that line sothe unit see's it as a high untill pulled low by a ground applied tothe x pin.

here you have "hot to do it"

[Q] Car Dock (or lack of) Recognition?

This has happened a few times now where I plug in a generic charger in my vehicle and I get a message in AutoGuard that it says it's recognizing a car dock.
So that brings me to the question, how does it recognize that there's a car dock? I'm guessing in the genuine Samsung Car Dock there's something in the dock itself that tells it it's a dock. But with that said, how come it's periodically recognizing it when I use a cheap generic car charger?
Strange...
Any tricks to let it go into car dock mode when plugging in a charger in my vehicle?

[Q] Charge & AUX for Car

Does anyone know of a cable to do both charge and output audio to 3.5mm (AUX) using just a single USB connection? Trying to regain the ease of use of the dock connector on my old iPhone.
I found a Motorola cable that appears to be the right thing, but likely wouldn't be compatible with the Nexus 4:

[Q] How do I select wireless charging over USB charging?

How can I disable USB charging on a rooted S4, or rather default to wireless when both are connected. Yes, I have read the posts about cutting the 5v wire, but want a less permanent solution that still lets the usb port function normally.
I have the Pioneer AppRadio 3 and use my phone for maps/GPS and pandora in the car. When the MHL HDMI cable is connected, it only charges at ~500mA (due to need to transfer data) which is not enough to compensate for the display, bluetooth and cpu usage, therefore my phone discharges when connected while driving.
I installed a wireless charging pad and receiver rated at 1000mA, hooked it all up to a hardwired 5V 2A power supply, and when it is in place, the phone charges as expected until I plug in the MHL HDMI cable. It then disables wireless charging and uses the ~500mA from the cable instead.
The MHL HDMI and bluetooth connection are required for the radio system to function.
Since it chooses USB over wireless when they are both connected, there should be a setting buried deep somewhere to affect which it chooses.
Any help is appreciated.
Cheers,
Brad

Dash install noob - Any experts willing to advise?

I have a Nexus 7 (2012) that I want to do a dash install with. I would like to retain my head unit (already relocated) for audio, and I have a few questions.
I mainly want the following features:
-USB Tether
-Bluetooth OBD
-Airstream (or otherwise) phone calls from iPhone through Nexus
-WIFI backup camera
-Bluetooth keyboard?
From what I've been reading it appears Timur's ROM is the way to start. It looks like with an OTG cable and a usb hub I can easily do usb tether.
I have a bluetooth keyboard that has its own USB dongle, I'm wondering if with that dongle I can be connected to the keyboard and the obd transmitter simultaneously
I saw an app that was available years ago to support airstream, but it seems to have disappeared. Does anyone know a way I can have the audio/mic go through my nexus for phone calls while driving? (Right now I use Bluetooth through my head unit)
I found the following parts, is there anything I need to avoid? Or anything I'm missing?
Tendak (Pack of 2) Micro USB 2.0 On-The-Go (OTG) Cord Cable Adapter with USB Power for Cell Phone Tablets
ORICO MPU-5S Auto Universal converter car inverter 12V 5 port smart charger for iphone 5 5S Car Charger Adapter By AFUNTA
Turtle Beach Audio Advantage Micro II USB Analog & Digital Audio Adapter
I'm still trying to do more research on backup cameras, and the possibility of a dash camera. If anyone has any input on any of this I would greatly appreciate it! Thanks in advance and I look forward to being a more active member of the community!
