I had same issue but never found a Joying update with a fix in it.
My solution was to disable the head unit bluetooth sync to my iPhone, but use a separate Gmail account for the Joying stereo, which syncs to google over a 3G dongle powered by USB. I then copied the contacts I actually need in the car from my main account to the new "joying" Gmail account !!
Now the HU syncs to google but leaves my iPhone intact !! This also keeps Car HU app downloads in a separate account to any android phones & tablet I use elsewhere !!
