Summary: Let's face it: using your iPod in your vehicle just isn't as simple as it should be. Unless you're driving a 2006 model year or later vehicle, chances are that your vehicle's stereo head unit doesn't provide any easy way for you to connect your iPod (or any other digital music player, for that matter). That means that you only have three options for listening to your iPod through your vehicle's stereo: direct connection to your head unit via an auxiliary input, a cassette tape adapter, or an FM transmitter. Most automobiles don't offer an auxiliary input jack on the front of their receivers, and connecting your iPod to a rear aux input--if your unit even has one, that is--is a complicated process that involves removing your receiver and (sometimes) part of your dashboard as well. So even though this setup offers the best sound quality, installation can prove difficult...or impossible. On the other hand, cassette tape adapters provide a far simpler and good-sounding method to connect your player, but they only work if your vehicle has a cassette player. So if neither of the above solutions are an option for you, then you have to begin considering either (1) purchasing an aftermarket, iPod-friendly head unit or (2) looking for an FM transmitter, and that's where the Belkin TuneBase FM for iPod comes into the picture.

If you decide to go the FM transmission route, you really can't lose with the TuneBase FM. Not only does it transmit the audio output from your iPod to an FM frequency you select, but it also provides a convenient dock for your iPod that even charges your iPod while it's in use. Many all-in-one solutions such as this are poor performers all around, but the TuneBase FM fulfills all of its duties superbly.

It goes without saying that the most important element of the TuneBase FM's performance is sound quality. After all, it doesn't do much good to dock and charge your iPod in the car if you can't listen to your music. As FM transmitters go, the TuneBase FM does an admirably good job getting audio output from your iPod to your vehicle's stereo, but it is plagued by the same sound quality issues that affect all FM transmitters. I live in an area that has a pretty crowd frequency spectrum; there are only a few frequencies that are relatively free of other transmissions. Despite this, however, the TuneBase FM still manages to transmit a clear audio signal to my receiver most of the time, although static can be a problem from time to time. I commute almost forty miles one way to work everyday, and I rarely have to switch frequencies, which is pretty impressive. Your results may vary depending on how crowded the airwaves are in your region. Compared to my last FM transmitter, a highly-rated iRock! BeamIt model, the TuneBase FM transmits a slightly clearer and more powerful signal. You won't get a much better FM signal from any other FM transmitter.

The TuneBase FM's other features are what really make it stand out from the rest of the crowd. Its docking solution, utilizing a flexible steel \"neck\" to support the cradle, is much more elegant, flexible, and pleasing to the eye than other solutions that use a series of thick, jointed plastic connectors. This allows you to position your iPod just about any way you please, and it also virtually guarantees that this dock is adjustable to fit just about any vehicle on the road. The dock is secured by inserting the base into a free power or cigarette lighter outlet, which is also how the device receives power for charging the iPod. Included in the box are plastic and rubber outlet adapters to ensure a snug fit in just about any outlet, and this seems to work quite well; even over bumpy roads or terrain, my iPod remains firmly upright in its cradle. It would be nice if the adjustable neck were just a couple inches longer (this unit includes a four-inch neck, the TuneBase FM for iPod nano includes a seven-inch neck), but a longer neck would likely be too flimsy to support heavier iPods such as the 60GB and new 80GB 5G video iPods.

The TuneBase FM automatically pauses and powers down a docked iPod when it the power supply to the device is interrupted, and it powers up the iPod and resumes playback when power is restored. One note about this: there is no on/off switch on the device, so it remains powered as long as the vehicle's power outlet is powered. If your vehicle's power outlets deactivate when you remove the key from the ignition, then this is not an issue. However, if your vehicle (like mine) powers your outlet(s) continually (even when the vehicle is off and the key is removed from the ignition), you need to remember to manually turn off your iPod when exiting your car or risk draining your car's battery.

Tuning to different radio frequencies with the TuneBase is a simple exercise. The device interfaces with the iPod through its dock connector, so it is able to display frequency and present information on the iPod's own display, which is much easier to read than a separate LCD readout. Tuning options are very flexible. In addition to four presets (which, if you sync with the presents on your vehicle's receiver, makes channel-hopping a breeze), the TuneBase FM allows you to to any frequency from 87.9 to 107.9, including broadcast-free even-numbered frequencies such as 88.8, 96.2, etc.

I only have a few minor complaints about the TuneBase FM for iPod. As I mentioned earlier, there is no on/off switch to accommodate vehicles with continually-powered outlets and cigarette lighters. I haven't experienced any difficulties with leaving my TuneBase plugged in for extended periods of time as long as I manually power down or remove my iPod, but it's an unnecessary extra step that I shouldn't have to take. It's also unfortunate that Belkin does not include auxiliary input and output jacks for direct connection to supported receivers or the ability to use the TuneBase for other digital media players and not just iPods. There's even a spot on the cradle specifically for an auxiliary jack; Belkin just decided not to include it with this model. That's really too bad, as I would have been more than willing to pay an extra five dollars or so for the added functionality of an auxiliary jack.

Overall, however, the TuneBase FM for iPod is an excellent product. If you have decided that FM transmission is your only option for in-car iPod connectivity, then this product is definitely worth considering and will perform admirably.

Summary: Just picked one of these up from our local wholesaler, after reading the reviews here and deciding this would be a good replacement for my iTrip, which sadly the connectors broke on. I have an iPod Mini.

Initial testing proved difficult to complete as my iTrip had been using 87.9, but the TuneBase doesn't go that low. As other reviews indicate, static can be a problem, and living in a metropolitan area makes it difficult sometimes to find a frequency that works and is relatively static free.

After perusing the manual and seeing that I could adjust the transmit volume, and bumped that up to its maximum setting (5). I got to wondering what wasn't talked about in the manual, and found that if you press 1 and 4 together (as for adjusting stereo/mono and the transmit volume), you can select US or Japanese station frequency ranges. The Japanese frequency range is lower than US FM transmit frequencies, but overlaps in the low 90s range. I used this to set the frequency to the one that I know works well because of my work experience with the iTrip, and programmed that into a preset memory on the TuneBase. I then changed the locale back to US, and it remembered the frequency setting just fine - and now the signal is strong and clear, with a minimal amount of static or chance of interference.

Summary: The user programmable 4 channel tuner helps to quickly find the strongest open signal. I like the all in one design (Dock, Charger, and FM tuner all in one piece). I agree with other posts that the materials used seem to be of a good quality and feels like it will last. In my 2000 Chvy Tahoe, it would be nice to have a longer extension. I'm not sure if the few issues with static that I've had are related to the device, the busy LA FM market, or the fact that the device sits so low in my dash that the dash shields the signal to my outside antenna? The sound quality is only crystal clear on occasion, there is usually some barley noticeable background static (which I can hear but others don't seem to realize it). However, I do believe that this is the strongest FM transmitter currently available and is by far the most attractive and discrete. If you don't have a built in ipod jack like my wife's BMW, this is the next best thing for listening to, charging, and securing your iPod in your car!!
