2015 Sonata Sport Radio Upgrade
 

How do I upgrade the standard radio to the bigger touchscreen with CarPlay? It's my first time doing this I don't know what to do. Do I need to buy extra wires? I already found the radio and found the DP-7363B Din Dash Install Kit.

If I might, before purchasing any replacement radio, check with a dealership service dept .

The reason for this is; vehicles starting around 2008 incorporated a new system called CAN, "Controller Area Network".
The network consists of several modules that report to the main vehicle computer. If the network is altered or malfunctioning, it can cause all sorts of problems including no start problems. In some vehicles , the radio is one of the modules. Take it out and replace it with one that is not compatible and the can of worms has now been opened.
That is why you should check with a dealership service dept. They get the altered vehicles and can tell you whether it can/will cause problems for you.
