No Radio signal - Denon DRA-455 Receiver

How do I refresh my XM signal?
The refresh signal will be sent from a satellite, so make sure your vehicle is outside and your antenna has a clear view of the sky. Turn your radio on and tune to Channel 184 for Sirius radios or Channel 1 for XM and SiriusXM radios. Simply tune to Channel 4 to verify your signal. http://siriusxmca.custhelp.com/app/answers/detail/a_id/252/~/resending-your-radio-signal

yeah you need the antenna for the gps

Step 1:

CHECK OP (Check Operation) means your radio has not received any type of
SAME alert signal (include test or demo signals) for about 10 days.

Make sure the antenna is fully extended and the stored location is correct. See
"Programming Locations and SAME Codes" on page 9 for more information.

Step 2:

Here is a link to the manual

I have a quite simular problem !
What`s realy strange is that when the lights are off, it`s seams ok, but when i turn on the lights (park lights ore full with xenon) the signal strenght is much worse ?

Anyone heard abot this problem ?

By the way, i live in Norway.

usually batteries...am takes less juice.....battery strength will affect fm signal strength

No not the radio...i thing the ear hones are malfunctioning

It is due to the vehicle antana. you need to purchase a antana booster. hook it to a 12v power plug antana from car to one side of booster and radio to other side. this will increase signal from car antana to radio and should fix problem. most boosters can be found at any car audio or truck stop and run from$10.00 - $25.00 good luck

When its in the car dock, the Inno sends an FM signal to the car radio. It does not receive a signal from the car radio. You must have the external antenna correctly installed outside the vehicle for the Inno to work. The built in antenna is disabled when the device is placed in the car dock. Make sure to test it outside, since garages or car ports will block the signal.

FM radio works the same way that AM radio works. The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied. FM signals have a great advantage over AM signals. Both signals are susceptible to slight changes in amplitude. With an AM broadcast, these changes result in static. With an FM broadcast, slight changes in amplitude don't matter -- since the audio signal is conveyed through changes in frequency, the FM receiver can just ignore changes in amplitude. The result: no static at all.
For sellecting frenquencies, go to radio, options, set frequency and search...
Good luck!
