For those who drive older model cars, the simplest way to bring it up to date is to install a head unit with Apple CarPlay/Android Auto and add a reverse camera. We always recommend this as it is highly functional and is money well spent. of course, we always push for a dashcam first if you don’t already have one installed.
The JVC KW-M560BT is perfect for those who don’t want to spend too much money but want a reliable and functional head unit. Of course it doesn’t come with higher end tech such as HiRes audio, wireless carplay and such, but we have other models for that, not to worry.
