Nissan radio reception

Sounds like an antenna issue, any radio installation shop should be able to check that for you.

go to a radio installation shop and have a test done on the aerial and wiring. It may be in the wireless and needs tuning properly on the bench

There is no Am anymore only FM, you may pick up bit but nothing good!!

I had the same exact problem. Toyota changed the Amolifier that improved sound quality but not the FM Reception.

THE HARNESSES CONNECTING ANTENNA TO RECEIVER (TWO OF THEM) HAD IAASUES. REPACING THEM FIXD THE ISSUE. FM RECEPTION EXCELLENT NOW !!!!!!!

Most radio reception problems that occur only while the car is running are caused by damaged diodes in the alternator. It can be difficult to diagnose this since most dealers and repair shops will not disassemble the alternator to test the diodes. If you can find a shop that rebuilds alternators they can test for bad diodes and replace them if necessary. Hope this helps.

try takeing back out and see if the conection on the back has come off if not have a look at the conection its self

Check antenna connections at radio and antenna assy.. Poor connections will only receive AM and hardly any FM

If the antenna is on the front, pop the hood, and locate where the antenna wire connects to the bottom of the antenna and make sure it is connected well. If everything checks out there, you will have to pull the radio from the dash, and look at the back of it. There will be a large black wire by itself connected to the radio. Push it in to make sure its connected as well. That could really be your only problem unless your radio happens to have a fault on the inside which is extremely rare. Hope that helps

use a coat hanger

This problem is caused by most commonly by a poor Antenna ground, and 2nd the radio chassis ground.
