Wont connect to car stereo

[Shane_10_]

I have the Pioneer AVH-X3800DAD eith the spotify application on the stereo so i can connect it through the stereo and choose my playlists, but for a few months since the update i can not get it to conmect to the stereo, i can get it to play through normal Bluetooth but not the spotify application on the stereo, can anyone help with a fix to this? Thanks
