can you play music over your phone's bluetooth? phone calls work great but i can't get it to play music...maybe the app sux?

You can however not with the factory system, and you loose a lot of audio quality doing this as well. Add to that draining your phones battery pretty quickly and I would go with an aux input.

I have the Bose system with an android phone. I use my Bluetooth for radio sometimes. You might have to set up your car to also play music I had to do that. I would give detail instructions once i get to a Pc.mi can't do this on my phone.

Edit: Your phone must support A2DP once you pair your phone to your Bose system push your function button until you get to Bluetooth then go to you phone Bluetooth options and make it will prompt you to pair the A2DP. I believe that is how I set it up

And plugging your charger into the 12v outlet eliminates battery drain.

Problem is that on some phones you drain more than what you can charge in the car.

I did not know that, Or that it was bad to keep it plugged in while playing music, as matt pointed out.

True but it's actually not good to charge your phone in the car, let alone keep it plugged in while playing music.

Why is it not good to charge your phone in the ar?

Because the chargers are usually higher amps than a normal house charger, which tears the battery up after a while.
Even if it is the correct charging amps its still not good to have charging on and off as you stop and go places.

I have to disagree. That would have been the case 3-4 years ago but most cell phones "remember" their previous charging state. With current technology both the battery and phones operating system regulate the the charging and it doesnt matter how many times you plug and unplug it.

You want to save your battery and wear-and-tear on your phone? shut it off at night. most people dont realize that having their phone on 24/7/365 wears it out.

and to answer the OP's question:
Keep it simple Go with this This

It actually still is the car with lithium technology today with phones. A lot of people do not realize this. With phone batteries being sensitive to temperatures and higher amp input to them, it can wear out a battery more quickly than a normal OEM charger. Same thing with (electric cars) they do not recommend rapid charging them to many times. Also if you shut down your phone you can actually get a fuller charge than having it on.

Guys,

Cell phone batteries are mated specifically to the phone, therefore the phone has a unique regulator/temp sensor/voltage monitor that controls every aspect of the phone's battery. You can't "overcharge" or "overcurrent" the phone battery.

Each battery has a discharge curve, that curve is managed by the battery IC in the phone, there is a maximum that cannot be exceeded.

Each phone also has a charge curve, that curve is also managed by the battery IC in the phone, there also is a maximum that cannot be exceeded. This battery IC also monitors ambient temps and the temp of the battery and will decrease charge current based on battery temperature vs. ambient, a certain rise above ambient will trigger a change in the charge voltage/current curve.

Look at the current rating of the phone charger that is the maximum current the phone will use to charge the battery at the acceptable nominal rate AND run the phone and screen etc., so the user can charge and use simultaneously. The 5V USB voltage is used by the battery manager as follows:

Inside the phone the battery manager system monitors the battery voltage, there are these circuits called a buck and boost, they take the 3.7 volts and by means of a switching supply very efficiently increase/decrease the battery voltage to what ever level the circuitry of the phone requires. Usually the core of the SOC requires about 1.8 volts, other ancillary circuitry requires 3.3, and other parts - the radio transmitter etc., may require more than 5 volts.
What you also cannot do is drain the battery down too far (all phone batteries are 3.7 Volts, and when the voltage of the battery is down to say, 3.1 or 3.2 volts the phone will turn off and the battery is "drained" to the customer but actually the battery is far from dead.

Each Lion/LiPolymer battery has a certain number of full complete charge cycles in is lifetime, when those are exceeded you will notice that the battery may charge but won't last as long, this is because the depth of charge decreases as the charge cycles erode the chemicals in the battery, the chemicals only last so long so after a while the chemical reaction stops at a level below what the phone battery monitor will accept.

Based on my experience, it's not good to leave the phone connected to a charger continuously, the battery seems to decay much faster as the chemicals in the battery cease their reactions and actually build barriers between each other, so I charge my phones during the day and leave them off the charger at night. Conversely, other people charge all night and are off the charger all day. YMMV.

Sorry to be so long winded but I wanted folks to understand charging - the car battery has nothing to do with the phone battery longevity.

I assume OP has a 2009, meaning you cannot stream music through Bluetooth

Try this and see if it works.
