After the iOS 10 update I lost bluetooth connectivity to my Pioneer DEC-X6800BT car stereo. I tried the usual remedies.
I think the real fix was initiating connectivity from the iPhone side rather than the Pioneer side. The DEH-X6800BT was never able to find my i6, but the fine print in the manual said the phone might see if it if “Visible” was enabled. I confirmed “Visible” was “On” for the Pioneer, the iPhone saw it, the confirmation number appeared on the Pioneer, I accepted that … pairing resumed. Now I’ll see how well iOS 10 car park detection works (requires bluetooth connection between phone and stereo).
Other things I tried (maybe they helped?):
- Usual wipe/delete connections on both sides.
- Reset Pioneer back to factory mode (not in manual, had to Google, trick is to power off, then push the menu button and look for reset).
- Reset network settings on iPhone
Incidentally, I really dislike my DEH-X6800BT. Overloaded controls, too many poorly managed and weirdly distributed menus, processing pauses that make Siri unusable when car manages interaction, awful ideas like color shifting panel and “MixTrax” etc. The manual is seriously incomplete. Get something else.
