I did a search to try to get some help but the other problems posted seemed a little different from mine. I just had an F900BT installed in my 2007 F150. The reception for both AM & FM is terrible. I have a seperate Sirius tuner in the truck & the install shop said that was causing my problem so they replaced the FM direct connect adapter as well as the Sirius cradle. The reception is still just as bad even if I turn the Sirius off & remove it from the cradle. My truck has a standard, stick out of the hood, antenae. Any suggestions on what to try? Thanks for the help.

I'm assuming the reception of your stock radio was good:

is there a chance that the installer did not connect the antenna to the Pioneer unit correctly?

Sometimes an adapter is necessary to interface your OEM antenna with the aftermarket headunit -- this may be defective or loose...

i have the same issue with my 08 charger. having an amplified antenna installed today.we will see if that fixes it

nope, that didn't fix it the installer is going to try some different adapters to see if that works. any other ideas?

ok after 2 to many trips to the stereo shop to try to fix the problem, i decided to look for my self. there it was plain as day.the blue power antenna wire was not connected to the blue power antenna lead.I connected them together and there you go.
