Bluetooth Profiles,Versions, Classes, and Features

Bluetooth stereo profiles:

Advanced Audio Distribution Profile (A2DP): also known as "Bluetooth Stereo Profile", allows stereo quality audio to be streamed from a media source to a connected device. Unlike the HSP, which does not allow for continuous audio streams, the A2DP allows reception of a streaming audio signal from the media source to Bluetooth stereo headsets.

Audio Video Remote Control Profile (AVRCP): provides a standard interface to control TVs, hi-fi equipment, or other to allow a single remote control (or other device) to control all the A/V equipment that a user has access to. AVRCP allows for easy control of another device that also has the A2DP profile.

Bluetooth Compliant versions

Bluetooth version 1.2 compliant means it is easier to use, a quicker connection, and interference is reduced! Bluetooth versions are backward compatible, so no worries as you upgrade to a higher Bluetooth compliant versions.
Bluetooth version 2.1 + EDR (Enhanced Data Rate) ADDS automatic reconnection with another Bluetooth device, increases audio bandwidth for better Stereo sound, and is becoming increasingly popular for battery life improvement of nearly 20% if BOTH devices have Bluetooth version 2.0 or higher.
Bluetooth version 3.0, High Speed! This latest Bluetooth version 3.0 fulfills the consumers’ need for speed while providing the same wireless Bluetooth experience only faster. Manufacturers of consumer electronics and home entertainment devices can now build their products to send large amounts of video, music and photos between devices wirelessly at speeds consumers expect, comparable to the 802.11 radio protocol.

Bluetooth Class defines Range

Bluetooth Class 3 radios use just 1 mW of power, with a range less than 2 feet.
Bluetooth Class 2 radios, typical in cell phones, have a range of up to 10 meters or 30 feet if unobstructed.
Bluetooth Class 1 radios, typical of Newer Bluetooth dongles and a few Bluetooth headsets, have a range of up to 80-100 meters, that's up to 328 feet if unobstructed!

Bluetooth Features to look for

DSP with Dual microphones will SUBSTANTIALLY improve the clarity of your in-car calls since the second microphone can sample background noise for the Digital Signal Processor (DSP) to eliminate the background noise better than any single microphone solution.

Multi-Point Pairing means you can connect to multiple cell phones SIMULTANEOUSLY, and on many car kits, even have two cell phones handling calls simultaneously!

TTS or Text to Speech With Text to Speech translation, you hear the number and/ or name of the caller before you choose to answer.

SST or Speech to Text TEXT while you Drive! Yes, now what you speak can be translated into text for messaging and emails with this nifty STT feature.

Can I use my Old car kit with my New Phone?

In Short. Not Likely.
The older car kits for most phones included a cradle that was specific to one brand and model combination of cell phone.
This is not how the game is played any longer.
Most new phones do not have a "car kit" specifically for them, unless they are a top end smart phones. (iPhone 4/ Blackberry/ Droid etc...)
For everyone else the New BLUETOOTH version 2.1 car kits are Bluetooth Enabled and are Awesome!
Bluetooth version 2.1 car kits are multi-point pairing, which means two phones can use the audio simultaneously! Not only are you NOT limited to using just one phone with the kit, but every time you upgrade the phone, as long as it has Bluetooth it works.
DSP with dual microphones will eliminate background noise very well.
ISO "Plug and Play" harnesses make installation quick, easy, and don't void warranties on your car or the car kit! Car kits also deliver the clearest audio possible through your car stereo speakers during a call, and resume music when the call is hung up. (If your phone supports A2DP Bluetooth profile, you can even stream your music from the cell phone to the stereo!)

We sell over 40 different car kits depending on the Bluetooth Profile of your phone.

So Is your old Car kit worth keeping....No.
Is it worth upgrading one last time..... I would say so.

For the BEST OEM "Plug and Play" car kit we suggest Scosche Blue Fusion Car Kits that allow steering wheel control and Stereo button controls for GM, Toyota, and Honda.

Then their is the Top of the line Bury CC9060IQ Touch screen and voice control that is so Awesome even the Government orders them and your Friends will want one too!
