In this thread and in some other threads it was mentioned that an iLive Bluetooth adapter was used for the Pandora streaming. I started with the iLive unit and I would say, it performs absolutely fine... However, for my setup I was looking for a BT adapter that would come on when an external power is applied to the adapter, without me pushing a "power" button to turn it on... The iLive unit had a momentary push button switch which needs to be pushed to turn it on... I even tried to "hotwire" the switch by soldering a bypass lead, but it did not help - the adapter still needed to be turned on after an overnight parking, which would make it an external piece, dangling in the car...
So, I started looking for a same type of an adapter but with a slide or a toggle power switch, so I could leave it "on" and have the adapter come on when external power is applied...
I found one here,
3 5mm Wireless Bluetooth Receiver Audio Music for iPod iPhone MP3 MP4 Boutique | eBay, and here is a picture of the unit - it is under $8 delivered, it is obviously a Chinese-made piece of cr..p, but iLive is made at the same place... this unit does what i wanted it to do - when the slide switch is in the on position, the unit comes on when the car is awake, thus I could hide this adapter out of sight and deal strictly with the 3.5mm connector... with time, I will hardwire the 3.5mm output from the adapter into the AUX input of the car, thus eliminating the danglilng 3.5mm wire...
