Singing the Kenwood Bluetooth blues

I think I can squeeze a  few more quality years out of my old designed-before-the-21st-century car. But I also felt that I couldn't spend them with a 20th century car stereo. So I decided to operate the audio system under the new management of a Kenwood KDC-BT752HD.

It's mostly been a blast. The HD Radio hype is finally a reality for me. For capable stations where the Kenwood can get  a strong enough signal for a digital signal lock, the sound quality improvement is very noticeable.  The USB port and Bluetooth connectivity means that I no longer need to tether my phone with an AUX cable to hear digital music.

If everything was perfect, then I might not have even been motivated to type up this blog. But it hasn't and I'm really posting this to possibly assist others that run into Bluetooth issues with this stereo. You see, a few times while paired with my phone, the audio has started stuttering. Last night, the pairing completely failed, to the point where the display gave an "HF ERROR 68" which the manual instructed me to remedy by performing a factory reset. But I had remembered reading a couple of reviews (versus many, many positive ones) on the Crutchfield website that alluded to some Bluetooth issues on this headunit model.

Well, I hope I've fixed the problem in a more permanent fashion, because it turns out that Kenwood has released a firmware update that is supposed to address Bluetooth pairing and Pandora stability issues. Oddly enough for the year 2012, the firmware can only be updated via a file burned to CD-R, and not a USB flash drive. Luckily, I still had a few of those around, and I followed the instructions to the letter, including the part about idling the engine while parked during the upgrade. The instructions say that it may take up to 15 minutes, and I got my "COMPLETE" message after about 12. Checking the firmware version on the display again confirmed that the device updated from firmware version 3.00 to version 3.01.

If I never post about this again, then it's safe to assume everything's peachy. If you've come here via some sort of search engine link, then I hope I've pointed you in the right direction in addressing your Bluetooth issues.
