Hi iam new to Dodge and i hope my english is good enough.
Last week i bought a 2DIN Aftermarket Radio and everything wents just fine but iam now stuck in 2 things:

Config:
- Dodge Caliber 2007
- The Head Unit connects with a typical iso wire harness. I also connected the radio with the ignition plus of my cig lighter.

They delivered me a Antenna Adapter and i was pretty confident to listen to the radio today, but there's nothing. I can't get any signal. My Harness (Blue Wire) is connected with the Radio On/Out. Any Ideas?
