The only way you will get track info on your radio screen is if your iPhone is connected directly into your radio. If your radio is only equipped to accept an iPod the only way you can use your iPhone is to plug into the auxiliary position using the cable as suggested. This is the way I play music in my car using my iPhone 5. If you use a dash mounted holder for your phone you can easily read the track and album information, this will also double as a hands free.
Try it , it works for me.
