Been through several phones..... but only 1 car stereo... the Pioneer 9800BT. Great stereo.. still works great... love it. As my phones get newer... it gets more and more difficult to connect via bluetooth. a few years back... all I had to do was turn the car on..... and the bluetooth connected... it was that easy. My EVO.... paired.... and I had it to where I just clicked the bluetooth toggle, and it connected automatically. The Photon..... wants me to enter the "0000" code every time I connect. I can connect it... and it works..... but shouldnt I get an option to "always" pair with the head unit? It won't work. If I turn my car off... it makes me go through the settings, connect, enter 0000 every time, etc. Its a PITA. Am I missing something? Is there an easier way?
