Screen won't flip when in the cradle

Replace the fuse, test the radio, then repair you inno prongs before inserting into the cigarette lighter again.

I feel your pain. Unfortunately, I haven't been able to find any car docks, there all discontinued. (sorry bums!)
But, when I'm riding my motorcycle, I put a rubber band around the radio and dock, holding it in place.
But, in a place that doesn't interfere with any buttons or the display.

I just spoke with Pioneer for this same issue. They said they do not repair the inno2 because it's not cost effective.

inno touch turn the power on ,but cannot open the program

I had the same problem with my Pioneer Inno Gex-Inno2BK XM radio receiver. One evening while leaving work, I gently took it out of the cradle & the screen suddenly went completely blank & all white. I could still hear music but there was no screen visible. Solution is this: (1) Gently remove the back cover which covers the battery. (2) Gently remove the dark blue square battery which is only about 1 inch (width) by 3/4 inch (height) by 1/4 of an inch in thickness. I removed mine by holding the receiver upside down & gently shaking it with one hand until the battery came out into my other hand. After about 4 or 5 gentle shakes, it came out. (3) Wait about 10 seconds. (4) Place battery back into XM radio receiver being careful to line the copper power receptable on the battery with a corresponding surface inside the receiver. Each copper area is only about 1/10 of an inch by 1/10 of an inch. Use this as a guide when putting the battery back in to make sure it's lined up properly. (5) Gently slide the cover back in place & let it snap into place. (6) Turn receiver back on by pushing power button like normal. (7) XM receiver should boot up with a full display just like new. All recorded songs are still in place. Nothing has been lost. Problem solved. Root cause of problem is probably some type of boot-up issue with the receiver in which the battery (i.e., the power supply) just happened to be slightly ajar...which also persisted even when placing the receiver back in the cradle until the above steps were taken. The steps above worked beautifully for me...Hope it works for you as well! Have A Great Day...Tom Armstrong

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.

I also had the white screen / blank screen problem on my Inno today.  I powered the unit off, removed it from the home cradle, and then popped out the battery for about 15 seconds and put it back in.  This fixed the problem.

I fixed the reboot cycleing problem by plugging the travel charger into the jack that also fits the home and car cradle. I had the Inno set to auto start when it was powered on in the car cradle. The travel plug must have over-ridden the auto-start setting and allowed it to finish the complete bootup. I then reset the Inno default settings and every thing was back to normal. I do not know what was the original cause of the rebooting cycle problem

Make sure it is docked in the docking cradle for the car. The option will not come up if the unit is not in the docking cradle.

What mfg and model?
