I had a similar issue with my old Q9c and found the following solution for it online:

THE Q/INFINITI HACK:
1. Install a local Registry Editor

2. Enable RAPI and user provided certificates so a registry editor will work

1. Navigate to HKLM\Security\Policies\Policies\
2. Click "Values" soft-key
3. Change "00001001" value to 1 (decimal) (recovery note: default is 2)
4. Change "00001005" value to 40 (decimal) (recovery note: default is 16)
5. Reboot device.

3. [OPTIONAL] Install Mobile Registry Editor on the PC to do the rest of the hack

4. Modify the HandsFree plug-in:

HKLM\Software\WIDCOMM\Plugin\HandsFree
i. Change SupportedFeatures to 45 (default is 1135)
ii. Add value HFBDA binary, set to same value as LastConnectedBda
iii. Add value HFDeviceType decimal 2

5. Modify the WIDCOMM bluetooth general settings:

HKLM\Software\WIDCOMM\BtConfig\General
i. Change bdaddr to (no value)
ii. Change DisableReopenAudio to 0 (default is 1)

6. Reboot device

Not sure if this will work for the TP2; any volunteers?
