Ich kann den iPod touch 4 nicht mit meinem Radio und meinen Boxen verbinden

Question

Guten Tag
Ich kann meinen iPod touch 4 nicht mit meinen Boxen verbinden, ebenfalls nicht mit meinem Radio. Mein Bruder hat den gleichen iPod und er kann seinen iPod auch mit dem Radio und den Boxen verbinden.

Google translate:
I can make my iPod touch 4 does not connect with my boxes, also not with my radio. My brother has the same iPod and it can also connect your iPod with the radio and the speakers.
Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- make sure the iPod is fully seated in the dock
- Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.
- Reset all settings      
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:                                                
iOS: How to back up                                                                
- Restore to factory settings/new iOS device.             
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.
