S4 won't pair with my car stereo

[awesome_andrew]

A while ago I got a cde-133EBT alpine stereo. It worked fine with my iPhone 4, but it wont connect to my galaxy s4. I go to my settings, tap bluetooth, then tap the stereo reciever, but then I always get an "error" popup telling me that maybe my pin is wrong, but it never gives me a chance to enter it please help me soon or I might switch back to the iPhone.

Hi,
Read the name of the stereo. It is : "CD/MP3/WMA Receiver Front Aux-in/Front USB for iPod/iPhone/Built-in Bluetooth". It is not built for the S4 and therefore it would not connect to the stereo.

I have a similar unit, I believe is called Alpine cde 72bt or something along those lines. Anyway - it says built for iPhone/ipod on that and doesn't mention android but works like a charm. Are you sure you're entering the pin correctly?
