Many thanks jarmo2!

Followed your instructions!
Next step is going to my car and test ;-)

Meanwhile I did some research:
PBAP documentation can be found here: http://www.bluetooth.com/Specificati...PEC_V10r00.pdf

And vCard format is described here: http://en.wikipedia.org/wiki/VCard

Maybe it helps for future troubleshooting...

EDIT:
Tested, but got the same result as before :-(

Tried to install hcidump to get some more information for investigation of what is going on, but get this:

apt-get install bluez-hcidump
Reading package lists...
Building dependency tree...
Reading state information...
You might want to run `apt-get -f install' to correct these:
The following packages have unmet dependencies:
mp-fremantle-generic-pr: Depends: obexd (= 0.18-0maemo5+0m5) but 0.28-0maemo3 is to be installed
Depends: libopenobex1 (= 1.4-0maemo3+0m5) but 1.5-2 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Unfortunately "apt-get -f install" did also not work.

Wanted to restore original state and install hcidump from there before starting another try, but restore fails also:

apt-get install libopenobex1=1.4-0maemo3+0m5

Seems like I am stuck, any ideas how I can proceed from here anynone?
