Pioneer GEX-P10HD tuner connected to AVIC-F90BT stopped working. AV sources show HD Radio but when selected that last station listened to is displayed with no sound. I'm unable to change stations or make any changes to the HD settings. Normal AM/FM radio works perfectly. Strangely, the HD radio stopped working soon after reactivating MSN Direct.

The problem with the screen coming out, buttons not working,screen not showing anything..etc. all have to do with the flex cable. Pioneer does repair it for free if it hasn't been sent in yet, but other than that its a $200 fix. I repair many of these every week and pioneer quit selling the part. I have 1 guy that I get them from but they are about triple the normal cost.

HI,

I'll let you know if there is a factory reset button button for this model.

Pioneer has a repair service center in California. Look up warrenty and service repair on their site. With a problem that detailed it realy cant be narrowed down to one thing. The good thing is you have enough wrong that you actualy benifit from their flat rate fee's for repair.

Me on the other end ended up paying $200 for them to replace a fuse. :( So yeah look up the repair centers number, give them a call and they will tell you what you need to do. The unit is repairable.

You need to go through the AV settings and change the Input 1 to IPOD.
