Bluetooth stack from vzw Treo 700wx install for other treo 700wx and 700w.
==========================================================================

This cab installs the vzw 700wx bluetooth stack. This is a one step 
install.

Preparation:
Copy the vzw700wx_a2dp.cab to your storage card or some temp folder. 

For best results turn off bluetooth and do a soft reset before installing
to avoid locked file issues since this tweak installs over top of the existing 
bluetooth stack. Also press and hold your Ok button to get to the task manager
and close any running applications (especially Active Sync).  

Steps:
1) Use File Explorer to run the cab file.  The cab install makes
the necessary registry changes and installs the rom files to Windows.
The install will ask if you want to install on the device or storage card.
If you have a sd card then choose storage card, else choose device.

That's it!

Turn on bluetooth and pair your stereo headphones. You may need to select
Wireless Stereo from the bluetooth device list. Click and hold on the 
device name to get to the popup menu to select Set as Wireless Stereo. 

Play some songs and enjoy!


UNINSTALL:
Steps:
1) Go to Start-Settings, select System tab, click on Remove Programs.  
Select "hannip vzw 700wx A2DP" and click on the Remove button.  
Soft reset.
