I own a 06 400h and absolutely love it. I recently had the regular battery replaced (not the hybrid battery). After replacing the battery my BT got flaky. At one point the car wouldn't connect to my phone and wouldn't pare with six other phones that I tried including blackberry's, iphones, and flip phones. For the record, the dealership also couldn't pare a number of different phones that they tried. The dealership was able to finally get it working however I'm not sure I fully understand the result. The dealership told me that the BT problem was a problem with my phone (Blackberry Curve) and that my phone was causing other phones to fail when paring with the car. Has anyone else experienced such a weird issue?
