Went to the shelf and picked off a Sony auto radio to install in my Rav. I think I bought it in late 2012. Anyway, it went fairly well, had to remove it once because of a faulty connection to the right front speaker. Audio works well. It has bluetooth so I was quite excited to pair it to my Galaxy S5......it didn't..
. Went through all kinds of gyrations and no luck. It will pair to my wife's S4, though. I'm thinking it's the OS on the phone as there have been quite a few issues with bluetooth and that OS (5.0). My wife's phone is 4.4.4. I can either regress it back to a lower level of OS or wait for 5.1 to come out sometime this year I'm hoping. Some say 5.1 fixes some bluetooth issues. If that doesn't work I may replace it with something more current and has HD capability. I can play my music on the phone as there is a jack on the front I can connect to.
Update: The bug in the sw was me. I didn't look beyond the first screen, the radio was showing up on the second page.
