I am thinking about replacing my am/fm stereo reciever (not sure why we still call them that anymore, all I do is stream music from my phone.) My current Alpine unit has great sound but has always been a bit difficult to operate, especially the bluetooth function, it often decides on its own to go on walkabout and refuses to link with my phone. I have to power it off at the panel and restart it, losing all the presets, and then re-pair it to the phone. Other people also have trouble pairing their phone to it so we can only play music from my phone. Been doing this for years and I am getting tired of it. Also, the usb port has decided to pack it in. The speakers and amplifier work well so no need to replace them, just want to pop out the old unit and replace one with the same standard cutout. Current unit is an Alpine CDE-HD138BT so a standard number 1 DIN chassis size, (W x H x D) in 7'' x 2'' x 6-3/8'' Who out there likes their stereo reciever? Are the new ones any better?
