Just bought a used manual 2005 with reasonably low miles.

That being said,... I would like to get some more 'functionality'. It has a no frills stock stereo system. I already have a set of aftermarket speakers that will fit. I'd love to have apple CarPlay like I have in my 2017 Silverado, but am willing to either keep the stock look and get some connectivity, or add an aftermarket HU. Something that's not too flashy and look out of place. Sounds like fitting a double din in these cars just doesn't look quite right. Was hoping a single din, which I can hook up my phone to and mount the phone off the back of the tach on the steering wheel.
Looking for what others have done. Thanks!
