I bought a Parrot CK3100 handsfree kit in the hopes that I can get it installed and working with my Samsung A900 (there are a few issues so far, one being that Parrot is trying to figure out how to get it to work with the A900 and I’m waiting on another connector as I have a wacky factory installed stereo). I wanted to see how hard it was to upgrade the firmware over Bluetooth. The utility, of course, is Windows only. No problem, I’ll plug my Bluetooth dongle into my Windows box and do the update. Not so fast. I had purchased a D-Link DBT-120 dongle awhile ago to use with my Mac before I got one with built in Bluetooth. Apple’s firmware update manages to do something to the adapter such that it can’t be used on Windows. After much searching and futzing, I was able to install an old firmware on it and convert it from HID to HCI mode and then got Windows to recognize it. Hooking up the car kit using a 12 volt adapter was pretty simple once I checked a few wiring diagrams. The firmware update went fine.Now all I have to do is wait for a firmware update (crossing my fingers that they can get it to work) and one more connector I ordered on eBay (I don’t want to cut wires to install this, so I bought a bunch of connectors to try to hook it all together.)
