install errors with win7

Its probably a bad pressure switch where the contacts did not open when the exhaust fan shut off. Check the pressure switch ports and verify there not blocked.

error message E-27

Some indash players wont play 16gb sticks. Try an 8gb one.

You must format the USB to FAT32..! Works for me!

I have found that cruzer flash drives uses a special format with it's own software. I found a format utility to make it the FAT format for a friends cruzer..

Hi Jazzy,
Please see the detail below for the said error codes C31:23.


According to the symptom and self diagnostic system the problem is in mechanical section (tape loading section) Therefore camera just need mechanical adjustment and will work fine again. This problem aries when the insertion of the cassette is improper or forced insertion.
Thanks for using fixya.

I had the same problem with my Pioneer AVH-P4000DVD. Just got my 16GB sandisk micro cuzer in the mail from Radio Shack. Here is what I did to solve it:

1. Copied all the files that came with the Sandisk device to another location (in case I need them again)
2. Copied all the music I had put on the Sandisk since I got it to another location
3. Using a Windows PC, I right clicked on the drive in Windows Explorer and selected "format"
4. I re-formatted the cruzer mini to FAT 32, default size (yes, I know it was FAT 32 already)
5. Copied the music back to the cruzer mini
6. Plugged it into my radio and it works GREAT! instant access to any track

Before you do this: Reformatting the drive also gets rid of the software that makes the cruzer mini copy files super fast. It will take a lot longer to copy music to the drive. For me this is no big deal as the only reason I bought the drive was to put a bunch of music on it and then leave it in my truck.
