Review on BXLIYER 10.1 Inch Android 10 Double Din Car Stereo Head Unit with DSP/Carplay/Android Auto - [4G+64G] - Includes LED Backup Camera Microphone - WiFi, Bluetooth5.0, Steering Wheel Controls, Mirrorlink Support by Brian Fisher

This unit is very impressive. It has good sound, the touchscreen is responsive and has decent picture quality. It's super fast, everything you touch is instant, and there's virtually no loading time. It easily runs most of the apps available on the Android store. The GPS is very accurate and does a great job of navigating no matter what app you're using. However, there are some disadvantages. DSP isn't really a DSP, at least as far as I can see it's just a graphic equalizer. Most annoying is the lack of a high-pass filter for the front and rear door speakers. This is a core feature of most car stereos these days as it allows you to block bass from the front and rear while still putting the bass where it should be. It appears to have a low pass filter, but I'm not sure how well it works because the amp does it for me. You need a 4-channel amplifier with a high-pass filter for your door speakers with this unit if you want a high-pass filter. This device is worth what they ask for and maybe even more. As with most of these devices, consider yourself a jack of all trades. It does almost everything, but not as well as something that specializes in that function. For example, it plays music well but doesn't have the same setup as a standalone unit from say Kenwood or Pioneer. It will do a lot more than Kenwood or Pioneer since it has Android built into it.
