The CDX series by Sony is a collection of CD-playing head units. The head units go from the basic model to one with the best and most desirable features. When replacing your current factory-installed car stereo system, use the CDX-GS500R as a good example of what is available in this series of car audio systems. The CDX-GS500R is the only model in this series with an app remote. It is the best model in the CDX series and is therefore programmed with most of the features offered by the head units in this series.
The Sony CDX-GS500R is a great-sounding CD-playing head unit that also comes with customizable features in regards to sound quality that help it stand out. The CDX-GS500R has a seven-band equalizer that gives you a good deal more control over sound customization than a basic model would. You have seven bands on which to tweak the sound to dial it in as closely as you can to the best sound in your car. Add the high-pass and low-pass filter controls, and you can fine-tune your car stereo system to your preferences.
The high-pass and low-pass filters really come into play if you upgrade the speakers in your car. The CDX-GS500R supports expansion of your current system with three pairs of RCA outputs at 5 volts of power per pair – one pair is designated solely to connect a subwoofer and amplifier. The low-pass and high-pass filters will help direct the right frequencies to the correct speakers, and you can tweak this even more with the control options.
Along with the CD player, the Sony CDX-GS500R also comes with a front auxiliary port and front USB access. Between these three inputs, this head unit can play MP3, WMA and AAC files. Also, it can play satellite radio with an adapter. The major downside is that this model doesn't feature Bluetooth.
