I have a 7290 and two cars fitted with a Pioneer car stereo which incorporates a bluetooth phone kit - which I tested with my 7290 and it worked terribly well - for a while. After a while both Pioneer stereos started losing connection with the 7290 (but worked fine with other bluetooth phones) so I changed my 7290 for another one - again fine for a while but now the new 7290 is starting to drop connection as well. Having tested the car kits with other bluetooth phones and having changed the 7290 I'm being compelled towards thinking that the 7290 has a problem which is not confined to one handset.

Has anyone experienced this or does anyone have a view?
