Greetings all,

I have a 2006 Quest and the backup alarm went out on it a while back and I had not attempted to find out how to fix it until recently. I ran across a thread over at Titantalk and got the idea that maybe it was just the buzzer/speaker that was my problem as well. So I went on Ebay and looked at my options and found the units for $40-$50 but then I noticed that someone was selling just the speaker sans plastic case for $36 shipped. They showed the front of the speaker but not the back (where you would be able to see the maker and model number). I figured that this little speaker could not possibly cost $36, so I googled the image and found a picture that corresponded to the back of the speaker which had the maker and model number on it.

The speaker is made by a company named BeStar and the speaker is their model BMS3650L-P2-HT LF. I contacted Bestar’s US representative in Arizona via e-mail and inquired about this part and was quoted a price of $10 for the speaker and $6 for shipping and handling, so I ordered one. It arrived in a padded envelope yesterday and while I expected it to just be the raw speaker like in the $36 Ebay auction, what I got was the whole unit, including the plastic housing that is identical to the one in my van. Last night, I popped the instrument gauge cover on my Quest, took the cluster loose, and installed the new speaker in place of the old one, and now my backup “sonar” system is working.

So, if you don’t want to go the Radioshack route and buy a small speaker and solder it in place of the existing one but don’t want to spend $50 at the dealership, here is the person to contact:
