Hi,

I just found this forum and joined. I have a factory Pioneer OEM in dash unit. Having several problems. The AM and FM has issues. When it's hot out the AM and FM does not work. During Winter when i first start the car AM and FM works. I can drive for hours and it works. If  i pull over and turn off the car and restart AM and FM will not turn on again. If i start it during winter radio works and if i turn the car off and turn it back on radio does not work. At first i thought it was a cold solder joint since it works when cold and when it's hot it does not BUT when it works when cold and i restart it , it will not work so this cold solder joint is not valid. I checked all connections on the head unit and all is good. Since the AM and FM was not reliable i signed up for serius radio. I have no issues with sirius,the CD and the navigation system. Sirius was working great for the last 2 months and then last week i lost Sirius....... also lost the Sirius Icon on the radio. That is weird. I took the radio apart and checked all connections in the radio. Put everything back togheter and same issue. Not to concerned about the AM and FM but i dont understand why Sirius stopped working. Any clues? OOOPS... Model should read Avic-X9310BT
