Installed on a 1985 mustang. Would have installed great, but the prior owner destroyed the radio area and I had to rig this up to make it work.

This item was purchased on September 28th, 2014.

For the past month and a half the unit has performed flawlessly. Unfortunately today (11-14-14) while I was driving the head unit locked up, and when it did so it emitted an extremely loud buzzing noise through all four cabin speakers. The display turned blank and the buttons did nothing. So, I did the next logical thing and removed the faceplate....... To my surprise the awful loud buzzing sounds persisted! The only way fix the player seemed to be pressing the very small reset button hidden behind the faceplate on the unit itself. But, as you guessed - all of my settings (I was all the way back in demo mode) were completely wiped, and on a receiver like this, that is the last thing you want. All of this occurred while I was playing an mp3, a feature this unit is designed for.

Here is a youtube video which accurately reproduces this exact issue: (WARNING: Volume)

11-14-14: I'm currently in talks with Kenwood right now and waiting to hear a response.

--------------------------------------------------------------
Here's (what was supposed to be) a short list of pros and cons of the device:

Pros:

- Bluetooth Streaming/Phone and HD Radio built-in, no additional hardware needed.
- USB Front and Rear input.
- Front AUX Input.
- Commit 2 separate sets of sound settings to memory with recall option.
- Pandora and a host of other streaming music.
- Includes Microphone

Cons:

- Horrible readability in any sunlight - I cannot stress this enough.
- Convoluted menu system.
- Can't disable USB Front or Rear as a source.
- Seek forward & backward buttons are too small.
- Default seek modes for FM radio are straight up odd. Adding presets is far from intuitive and confusing.
- The visualizer is a half to a full second behind the playing audio and badly stands out.
- Nearly one full second of delay with the illumination that blinks with the beat of the music - seriously miserable.
- More than half of the time the SRC button beep sound doesn't work.
- Display changes are not device wide - it's all per input. So if you like your clock on each input, you have to manually add it to each input. Speaking of the clock, you can't use it while playing music without the laggy visualizer on.
- Can't save per input display settings or propagate display settings device wide.
- Bluetooth phone doesn't display callers name when calling you, only the phone number, even though in the phonebook their name is displayed properly.
- Autoanswer phonecalls is on by default?!
- Subwoofer is disabled by default while using bluetooth audio streaming and the option to enable it is called "Bluetooth/HFAudio" set it to "ALL" for the sub to work.
- Each time you enable bluetooth, the display lights up and says "HF CONNECT" followed by "DOWNLOADING". This seems unnecessary with an already paired devices.

Other:
- Bluetooth test mode greets you with the message "Please pairing your phone".
- Here is a video showing the latency between beats/sounds and response from the visualizer display:

I truly wish I had better things to say.

I bought this antenna in winter on a lightning deal, and just recently installed it by mounting it on the chimney of my house.  After finishing installation, I connected it to my TV & was able to autoprogram 66 channels.  Great, right?  Well, it was until it rained.  Now, the antenna is not functioning.  Since the power light on the antenna is not on, I'm assuming the water has knocked out the electronics.  I recommend to the manufacturer that if you advertise your product as an outdoor antenna, you actually build it to withstand the elements.  I will be getting a replacement elsewhere.

Got this to replace another Sirius receiver that died.  This is a nice unit and does everything I wanted it to do EXCEPT reliable FM transmitter performance.  Meaning this thing sucks if you plan on listening to it over an unused fm radio station frequency on your radio.  I tried every unused freq I could find and even installed the "helper" antenna they included.  Static, static, and more you guessed it static.  Actually I believe I read somewhere that the FCC made the manufacturers reduce the transmission power of all these types of units after complaints of cross signals...if that is true then it's going to be the same for all these units.  That being said I order the Sirius Professional Vehicle Install Kit SIR-PVK1.  It completely solved this problem and got rid of the need to use the cig lighter plug which is nice.  Bottom line...this is a great unit if you order the pro install kit.  Would be nice if they just included it but they don't.

Finally after I installed it, I then called Sirius...well needless to say Satellite radio is crazy expensive but whatever I tried it for a month. During that month I had more service interruption than I can count, if you don't have a completely clear sky above your car you will have problems: A tree will mess it up, A wire will mess it up, A cloud will mess it up, Rain forget about it...signal completely gone! I had several professional radio installation techs inspect and go over my hookup work and they said I installed it correctly yet it still failed to work properly. So I got tired of the problems cancelled my Sirius service after a month and dropped this off at Goodwill.

While it is a beautiful radio externally, apparently it is junk internally.  I haven't used mine in a while, it wasn't even connected to power.  Tried to use it today, and I get nothing but popping and intermittent high volume buzzing.  If you do your research, you will see that this is a VERY COMMON occurance.  If Henry Kloss was still around, it would be fixed, probably at minimal charge.  I would love for it to work, because it is a classic visual design.  But I have seen a few posts that say that Tivoli wants $100 to fix their radios.  If it is a faulty design, they should take responsibility for the product and fix it for customers at a nominal charge.  NOT 3/4 of the price of a new radio.  Tivoli Customer Care, prove me wrong, and I will change this rating.

I bought this radio less than a year ago, and I will start by saying that the sound quality was so far beyond my expectations. It seemed to be a really well built system. My problem that I have is from my own doing. I was BBQing, working in my yard, and jamming out to some great music from a great machine. It started to rain (not real hard), and I picked everything up. This radio is not as water resistant as you might think. I now have no volume control of the radio, and can't change radio stations.  I contacted my local rep and they basically told me that I'm SOL, and need to buy a new system. I emailed Dewalt about the situation,  and they referred me back to the local rep. This is very disappointing,  as I have another Dewalt radio that was bought in 2001, it has a cracked housing, stays outside, gets all kinds of weather damage, and still works. Check the weather before you take this outside, so you don't end up with a $200 20 pound paperweight that you will have a hard time throwing in the trash can. Things are not built the way they were before.

The cable was wired wrong, I tried to program a Baofeng UV5R and it put the radio in transmit and sent RF into the computer. I'm still not sure if any permanent damage was done to the computer, but it sure messed it up for a while.

For my 2013 FR-S, the  loop between pin 8 (for power antenna) and 9 of the 10-pin harness needed to be cut and the pin9 need to be connected to "amp turn-on signal" cable from the head unit. Unless doing this, the door speakers didn't work because those speakers are driven by the amp. The radio reception was also bad before cutting the loop.

The signal has been great.  This was a refurbished unit and I wondered why since it appeared brand new.  The antenna has recently begun to de-laminate and soon the antenna will be useless as I had it on a wall near a window.  I will probably buy another but it is disappointing since it has always been indoors.

There was no way to select which of the preset frequencies I wanted or needed and as a result the one I received conflicts with a previous instal that is nearby.

I own a 2012 Silverado WT with the most basic AM-FM stereo factory radio. Since there's no CD player or AUX input, all I wanted was the ability to listen to Pandora on long trips. Now in the old days, you'd go get a good aftermarket head unit/ all in one radio, a mount kit and a wiring harness adapter and swap.  The problem today, is that your 'radio' is a lot more than just an entertainment device- it's part of the vehicle's overall computer system and the display is used for operating diagnostics. To go aftermarket now includes a data adapter and usually headaches,
This brings us to the BOSS FM20- A metal box slightly smaller than a box of cigarettes with only a few wires. There's a +12VDC wire that goes to your switched "ACC" power, a -12VDC ground, a short antenna wire and 2 RCA female connectors for low power audio input.  Find a vacant FM frequency, program it into your radio, set the 4 DIP switches on the box (note switch positions!) do your electrical work and you're good to go.  Using a Samsung Rugby III as my source, I had no problems pumping tunes through my radio.
Overall I give it 4*, as you do get some hiss coming through at high volumes. My only gripe was the execution of the cables. The wires are soldered to the p.c. board and held in place with a dab of hot glue- a point of failure, especially in a vehicle.  A few Ty-Raps inside the box did the trick, but for pennies they could have put in some proper strain relief.
Considering the modest price and ease of installation, it's a good fix for the non-audiphile

I always research my products well enough before I buy. There are usually more than enough comments to make a safe decision. However, in this case, I am annoyed enough to write my own. Last week, the weather cooperated so, I decided to mount my K40 antenna on my pickup, which I purchased from Amazon several weeks ago.  I did all the necessary routing of cable under the chassis, into the engine bay and through the firewall and neatly connected it to my radio. Finally, I was ready to go through the SWR process. When I stepped back to examine my proud engineering feat I noticed that the antenna was slightly canted to one side, about 5-6 degree or so. I promptly jumped up to make the necessary adjustment. Much to my chagrin however, I discovered that I am not able to adjust the antenna side-to-side. I seems adjustments can be made only fore and aft. I have tried to contact K40 to request warranty replacement/repair but to no avail. "All customer service representative are currently busy. Please leave a message." RIGHT! Incidentally, I have mounted K40s (3) on various of my trucks over the past 20+ years but this is my first bad experience. The workmanship which I greatly appreciated in the past is simply no longer present, at least from what I am experiencing. In conclusion, I regret that I am closing the book on K40 and going to another antenna. If you are reading this K40, get your **** together.

Same story as Ed"Turns out the receivers inside the plug were not properly located. Had to take it apart and re-arrange/bend the receivers to get them in the proper position"

Had this antenna up for 9 months and radio stopped working. Disconnected the coax from back of radio and water came out.

Brought down the antenna and found that water was going into the two connector flanges where the 3 sections of the antenna connect to each other.

Appears the water actually ran between the antenna element and the metal chrome fitting connectors.

So, the water migrated into the actual antenna sections down to the antenna's coax connector, into the cable's connector and through the cable all the way to the back of the transceiver, and actually into the radio.

If the instructions had said to waterproof the antenna section connectors, I would have. But no suggestion to do this was made.

Was looking forward to using this CB but upon installation it was stuck on channel 19, wouldn't let me change it to any other channel, no squelch, no rf gain, even when connected to a properly ground k30 antenna. Switching the knob to Channel 9 or PA mode turned the display off. I've had luck with numerous items that have been used and even purchased a Uniden bearcat scanner used with no problems whatsoever so this was a surprise to me.

I bought my first satellite radio in my life in August of 2007 ( Sportster 4 w/ Car Kit) and my antenna went bad after a month (Message said: "Antenna not detected") Sirius was great about quickly sending me a replacement, though I had to pay another $30 in labor to have it professionally installed (again). Just over a month later, I am now getting bad reception with the occasional message: "Acquiring Signal" and no audio. So I called Sirius to get ANOTHER antenna and they wanted to send an entire replacement Sportster 4 w/ Car Kit, have me play around and find the bad parts and THEN ship the unused parts back AT MY COST!!! I could not get them to pick up the tab on an approximate $6 shipping charge. I don't mind paying this if this was the only time, but this is the 2ND TIME IN 3 MONTHS OF OWNERSHIP THAT THIS PRODUCT HAS GONE BAD!!!  Consequently, we had bought a 2nd Sportster 4 that stopped working in a week (the unit itself went bad) but they quickly sent a replacement to us. Seems like there's some quality control issues at SIRIUS.

***Addendum 4/2008: Had another antenna fail on me and had to replace it. Sirius customer service was quick to send a free replacement, and an install card to cover my costs for installing the new one. But I'm getting SICK AND TIRED of having to keep replacing these damn things!!!
