iTunes is does not Reflect my my Ipad2's Contents

[almanfra]

Hi Guys

When I sync my iPad2 to my Windows 7, I noticed that my iBooks in the iPad2 are not the showing everything in the iTunes Library. I suspect that it also happens with the other contents. I wanted to sync again but iTunes is saying that it will overwrite what's currently on iPad2. What I want to happen is to have all the contents on my iPad2 to show on my PC.

How can I make my iPad2 totally in-sync with my iTunes without buying 3rd party apps?

Thanks

Alfred

With iTunes open and your iPac connected, right click on the iPad in the Devices list and choose Transfer Purchases.

When it is done your iStore purchases should be in iTunes, and it should stop asking you to wipe the iPad. Also make sure you computer is authorized with the Apple ID you use for the iPad. You'll find that under the Store menu.
