All I need is the ability to connect my phone to my 2004 via Bluetooth for music mostly from Youtube (and phone call, as the existing Bluetooth drops off occasionally). Looks like both options can offer that, but the Sl3b is $230 and the Grom-BT3 is $135 only. Do you know if there's any known problem with the Grom-BT3, or why the Sl3b is much more expensive? Thanks

PS: I did read through the sticky about bluetooth audio connection.

 

Im using the bt45, it's been a blessing and took about 15 mins to set up and is nicely hidden in the dash

 

Yes and that usaspec bt45. I don't know what are the differences that make the prices. Anyone having experience with more than one can tell the pros and cons? Thanks

 

USA-SPEC BT45 is flawless for me, and was pretty cost efficient too. That'd be my pick.

 

Sounds great, it might worth a try. Did you buy it from Amazon or usaspec website? There's a huge price difference b/w the 2 places (Amazon is only $127 while usaspect website it is $229)

 

Amazon is not an authorized dealer for usaspec. Reviews say they had warranty issues and were not covered. I would still buy from Amazon though.

 

I bought from amazon been fine. Even if it conks out price is low enough to buy another
