This device is simply excellent. I struggled with adding in the extra cost for the cell phone call management. The cost difference is > $150, but in the end is worth it. It is very well integrated with handling calls, pickup and hangup are easily integrated with the CH +- on the steering wheel. In fact all controls work seamlessly with the steering wheel controls on my 2003 Accord EX (non-nav) head unit. The audio quality is terrific. Functionally the only issue I have had is that the audio levels for playing music are different from a cell call. You have to vol up for a call, and upon hangup you may come into a loud audio boom if you had music playing prior to the call due to audio resume.The installation instructions had one important error, they show that the connection to the radio is on the back, showing you have to pull the head unit out to connect their plug. On the non-nav accord head unit, this port is actually exposed on the bottom of the head unit, so you do not need to remove it. After you pull out the storage compartment below the head unit, you will see a port exposed from the bottom. Simply plug into there. Don’t even bother pulling the head unit, there is no where else for you to plug in. I was able to run the wires very cleanly and this unit sits next to the shifter on the carpet, nicely hidden under the console. Run the microphone cord to your desired installation and you are all set! For even a relatively inexperienced user, a YouTube video or two and you are looking at 1-3 hours max for a clean installation. The local shop dealer wanted nearly $1k for this install, more of doing head unit swap. Comparatively this was a cost effective and easy install - high value!Very happy with this purchase, hopefully it lasts!

Music Audio Quality:The music sound quality is near perfect, if not 100% perfect CD/iPod quality. It recognizes my device when I get in the car within 5-10 seconds without me having to do anything. Be careful not to leave your volume up too loud when you get out of the car, as when you get back in the car, the female voice that says "Connected" might leave your ear ringing for a second =)Phone Call Audio Quality:Exactly what you would expect for a car Bluetooth device. No better and no worse than anything I've experienced in any other vehicle that is Bluetooth compatible. I have my mic mounted near my rearview mirror, and I've never had any issues with anyone not being able to hear me, whether stuck in traffic or driving down the highway (windows up, of course... it's not THAT good). It is very nice how it integrates perfectly with my steering wheel controls. A simple press of the up fuction button on the steering wheel answers the call, down hangs up. If you are listening to radio, it will switch over to the AUX channel that your Bluetooth connection operates through so that the call can take place through the vehicle speakers. Note that when you hang up, it will stay in the AUX setting, so you will have to switch back to the radio if that's what you were on. Of course, if you were just listening to music through your phone via Bluetooth, which is already on the AUX, your phone will resume play of the music from your phone (at least my iPhone does).Note on iPhone Voice to Text:Speaking of iPhone, another thing to be aware of is when you are hooked up to Bluetooth, if you press the voice-to-text button, you have to wait 2-3 seconds to start speaking, as it is sending the signal through the Bluetooth connection and, thus, it is recording your voice-to-text through the Bluetooth microphone installed on the car. So, you don't need to hold your phone up to talk into it directly. That said, you do need to project as you normally would on a phone call so that your voice-to-text function can pick up on each word. You may even need to speak up a little more than you are used to. I use voice-to-text all the time, and while it does take a few weeks to get used to, I have no problems with it, and I'm picky about voice-to-text.Install:This works awesome in my 2006 Honda Ridgeline. The install was pretty simple. With that said, there are two ways you can install this in the Ridgeline. Option 1 is more complicated, but only necessary if you plan to keep your XM radio channel functional, as XM and AUX/Bluetooth need to share the same channel. Option 2 is much simpler, and perfect if, like me, you do not need XM radio functionality. I simply Googled how to pull the dash off (easy), pulled the head unit so it was loose in the dash and I could access the back (easy), pulled out the glove box so I could tuck the BT45-HON3 box back there (easy), and then clipped the microphone to my map light above the rearview mirror and ran the microphone cable under the ledge of the headliner and then behind the trim running up the passenger column (moderately simple). I was initially considering ordering this from Crutchfield thinking I needed to pay more for the vehicle-specific install instructions, but I'm glad I didn't. Resources abounded online, at least for my simpler hookup, and I know there are instructions on the Ridgeline forum for those doing the more complicated hookup.Conclusion:This is a great solution for the money for anyone who wants to be able to listen to music from their phone without having to mess with CDs, USB connections, or wires. 3 months in and I haven't looked back since I installed it. Pandora, Spotify, and Apple Music all play into my vehicle steering wheel controls seamlessly. The sound quality is excellent, and it is nice being able to take hands-free calls while driving. I was considering doing a complete overhaul of my audio system initially and I am so glad I didn't. I know the fact that the Ridgeline already has a decent sounding sound system plays into this, but if you don't want the hassle of having to install a new head unit and all that comes with it, you will be extremely happy with this regardless of your vehicle.

Update 8/13/20. I bgt this product in 2016 and the unit blacked out after 4 years. I pulled out the jack from the back of the unit and boom! Back in play! The dang thing is beast!! If this thing goes out permanently, I may have to get a new car. Lol. My Acura MDX is playing my music nicely as my phone conects seemllessly thru Bluetooth. 2016 review —> I ordered this product because I'm not ready to trade in my 2005 Acura MDX Touring yet. The truck has 140,000 miles and rides just as sweet as the day we purchased back in Dec 2004. Besides, we cannot afford an new vehicle at this point. My wife and I listen to pandora and Sirius through apps on our phone at home via portable Bluetooth speaker. The only problem we had which was pretty darn annoying was the fact that we could not connect through our factory stereo in the MDX. Bluetooth connection was not available for radio back in 2004. It would only connect for phone calls. We have a small portable speaker we would put on the dash board and connect via Bluetooth and it was not the same as listening to music via my Bose system.I ordered this product as I felt it was the only product which would meet our needs. Well! I was blown away and not disappointed! I watched a video on how to install the product. I ordered the item on Amazon on a Sunday nite. The product showed up at my door on Tuesday nite. I was so excited when I got home that I decided to install the darn thing outside my garage around 9pm. Lol. I used my iPhone over the visor as a flashlight while I began to remove the radio's double din harness. The removal was a bit tricky but simple enough. If your a handy person than you'll have no problem installing the product. I have an xm radio with no Nav so I had to install the BT-Hon behind my radio. There is no song tags as CD/AUX does not allow it. Only numerical tracks are shown. (Not a factor for me). After an hour and a half I was done! I ran the cable from the back of the radio and down thru the inside of the panel leading to the passenger side. Some people placed the box below the air conditioning controls above the radio. I decided not to as I would like to use the USB port behind the box and have it accessible (for charging only) so I decided to place the box under the corner end of the passenger side floor mat. I followed instructions to a tee. Running the microphone was the only nuisance as I had to run the thin cable from the inside driver side visor to the windshield frame down and across the front windshield tucked nicely so it goes unnoticed and down the passenger side and underneath. I never tested the item before I closed everything up. My confidence level was high due to some of the reviews I had previously read before ordering the unit. I paired the phone almost instantly. Just hit the CD/Aux button twice to get to the AUX position on your radio. Go to Bluetooth settings on your Celly and turn it on. Scroll down to the BT-Hon device and click on it. Your phone discovery will sound over your car stereo with "Connected." And boom! Your in! I raised the volume on my Celly so it will allow me to get maximum loudness from my car stereo. I click on the pandora app on my phone and began playing my music. I was blown away! WOW! I finally got my music life back in the Acura. Makes long trips bearable. (Regular radio tends to suk and has mediocre sound) I had discontinued my xm radio service years ago as it got to be so expensive. I have the app thru the family. I played it thru the radio and it was truly amazing. I played one of my playlists from my ITunes and was blown away once again. I do have great music!! Lol. I took the car on the highway for a final spin while I turned Aerosmith and enjoyed the clear sound of my Bose sound system. It's amazing how this small unit has transported my MDX radio into the current state of music listening in 2016. My MDX radio plays the same apps that my daughters 2014 Mazda 3 does. The next morning I had my wife pair her phone which took all of 1 minute. She played her pandora app and was also blown away. I called her on her cell phone, the ring was soft and the voice prompt switched from music to announcing the phone number coming in. I instructed her to hit the volume up tab on the steering wheel and the phone call was connected. She spoke and I heard her clearly on my phone. I spoke and voice was not overbearing in the car. It was very clear. I really can't say anything bad about this product. It is literally game changing. If you feel you cannot install yourself than spend the $65 at bestbuy and have them install it. Last two words: AWESOME product!!!!!UPDATE 11.25.2016:Still amazing! No issues at all. My wife actually watches music videos on her i-phone through her YouTube channel when we're on long trips and the sound is incredible. My Bose system still takes music to the next level. Please keep in mind the music suffers very slightly as its coming from an outside source but not enough to really complain. I just have to say... It is, what it is and we love it! I have recommended to friends and family and they are blown away by the product. Cheers and good luck!
