The new DDX9902S joins the ranks offering Google and Apple's unique brands of smartphone integration at CES 2015.
For users who already own an Alpine car audio receiver, the KCE-400BT offers an easy way to extend the functionality, safety, and usable life of the headunit by adding clear, hands-free calling and wireless audio streaming.
The vast array of features offered by the JVC El Kameleon KD-AVX44 creates a car audio experience that rivals all but the best preinstalled receivers.
At less than half what you'd expect to pay for a standalone device, the PLX Kiwi Bluetooth is a great OBD monitoring solution for the Android smartphone-toting car geek.
The Audiovox ACA250 wireless rearview camera provides an easy way to increase the safety of your vehicle while backing up, if you can deal with the wireless technology's rough edges.
The JVC KD-AVX77 El Kameleon is a great receiver for system builders, but the touch-screen interface isn't as easy to use as some of the competition's physical control schemes.
The Alpine CDE-102 is an excellent OEM replacement stereo, but serious audiophiles and system builders should look further up the product lineup.
The Parrot CK3000 Evolution is a cost-effective, feature-rich hands-free calling system. Its simple design masks some very easy to use options, including a great voice-command interface.
Android Auto is Google's new system for integrating Android phones with car dashboards, unveiled at its I/O 2014 keynote.
Google Glass for your helmet sounds good in theory, but in practice it's a bit lacking.
If you never plan to share it and will never use it in a loud vehicle, the HCB-105 is a good sounding, simple to use choice. Everyone else should look elsewhere.
Some may prefer a full headunit upgrade, but the Highway 300Di offers a powerful digital radio experience that will suit many drivers.
With its spring-loaded clamp, the Easy One Touch holds a phone firmly in your car, but allows for easy removal.
It's still the only way to get digital radio in the car. Those desiring the extra channels or improved sound quality will love it, if they don't mind the hassle of setting it up every time and have an auxiliary jack in the car.
For its price, the BlueDriver is a convenient tool for those who want some ability to work on and understand modern engines.
It has its share of annoying quirks and faults, but iQ is admirable for its impressive feature set and unique inclusions.
The CarCheckup System lets you monitor data about your car, but does not offer much in the way of tools with which to process the numbers and really understand how your car is performing.
It's far from perfect (scary warnings, difficult controls, occasional glitches), but sound quality, Bluetooth, device support and its aggressive pricing pushes it over the line. Just.
