Question: Will usb bluetooth adapter work in a car stereo?
Document: This adapter was easy to install and the software that comes with it is simple to use and it installed without a glitch on my XP system.I use it to connect to my Belkin F8Z492TTP Bluetooth Music Receiver (about 12ft distant) which is connected to my stereo system on which I play my music collection while I work.
I purchased this since the Iomega Bluetooth adapter would not work with myKinivo BTH220 Bluetooth Stereo Headphone - Supports Wireless Music Streaming and Hands-Free calling. I have connected this Kinivo BTD300 with my Dell Windows XP Laptop and my Windows 7 desktop. I was able to use Bluetooth audio to listen to music and make calls on my softphone on both systems. I love this adapter. I will be purchasing another so I don't have to swap it between my two systems.
Bought Kinivo BTD-300 Bluetooth usb adapter to connect my Acer Aspire laptop to a Phllips SBT-310B bluetooth speaker. It finally worked after prolonged trial and error activities with Windows 7. Once it finally began to work I've had no further problems. Windows 7 wasn't as clear or cooperative regarding installation processes as one would like.
It stopped working after 10 minutes, just long enough for me to install the drivers and attempt to detect something. I figured it might just be my computer as some of the reviews said it doesn't work on some computers. So I tried plugging it in 2 other computers and while attempting to install the drivers I was notified that the usb adapter was not being detected and thus couldn't install the drivers.Despite the Bluetooth adapter not functioning it would still light up.
After using a very cheap generic BT adapter for about a year, it started to fail - what do I expect for $1.37? I use it at work with my Rocketfish stereo headset, so for most of the time I am within 5 feet of the adapter. The difference between the two were like ragweed and the mighty oak. The sound was much cleaner, connected faster, and had better distance before dropping off.
I had just purchased a nice bluetooth headset but found that even though it worked fine on my iPad and iPhone it did not work with my MacBook Pro. I could listen in monaural but not stereo. This device corrected that problem.
The only disappointment I had with this product is that it requires installing software. I purchased this so I could listen to music on my work computer. However, since I do not have Admin rights to my work computer, I was unable to use this product and ended up purchasing the TaoTronics TT-BA01 Wireless Portable Bluetooth Stereo Music Transmitter, which connects thru the audio jack and does not require a software load or installation of drivers.
The device worked as promised on the iMac. No problems there. However on the Windows Vista laptop and the Windows 7 laptop not so much! Neither would connect to my bluetooth device, specifically a bluetooth headset with an audio profile etc.. Nonetheless I need this for the Windows environment not the Mac. Also on both Windows laptops I can no longer use my mouse with its usb transreceiver. After numerous uninstalls, reinstalls, etc... I have to use a corded mouse to conduct my work.
This adapter is working great and allows me to connect my laptop music player (Winamp) with the a greate Pair of Bluetooth Stereo Speackers. I can now play my mp3 music collection (16 gig) from my laptop.
I use this bluetooth adapter to play internet radio, and my music through Panasonic stereo that has bluetooth. Works really well. Also allows me to connect to my cell phone by bluetooth. Would recommend this item highly.
Answer: I'm almost positive it won't because you have to install the software on your computer to use the USB Bluetooth. It would be impossible to install the software in your car sterio. So I would say don't get this if you are trying to do that. But they do sell Bluetooth adapters specifically for car sterios. Search on google for a Bluetooth adapter for YOUR sterio and you should have a wide selection of different adapters.
