I got this to replace a very old Alpine tape deck! The old radio still worked perfectly but didn't have the modern features we all want. I wanted the USB and AUX inputs but all the other features are nice too, for not much extra money over the other models in this line. The bluetooth works great, paired up easily with an old iPod touch. There are a lot of available tuning adjustments but we aren't using them because we have an addon EQ. So far the only negative is the brightness of the power/source button even with the display dimmed. Surprisingly the old remote from the other radio works too!
Replaced an old Alpine tape deck in a '90 Chevy truck. The old stereo worked just fine but I wanted some more modern features... Installation was straight forward since there was already an aftermarket head unit. The Bluetooth paired easily and quickly with an old iPod touch. The 3.5mm aux jack and usb ports work well. The radio has RDS which is nice. Overall sound quality is good. All the color options for the display is a neat feature. I was even able to reuse the old remote control! It isn't 100% functional, can't turn the unit on with it but otherwise it controls enough of the functions that I won't get the proper remote. Biggest negative is the brightness of the power/source button.
