Radio dying?

My 2010 Prius has the basic radio with Satellite, AM/FM and 5 CD changer. It does not have the NAV system. Recently it's been intermittently acting really strange.
On a hot day when you start the car, sometimes the radio display starts showing what looks like a test pattern where all of the pixels start turning on and off in various patterns and it keeps blinking on again, off again. Often, I'm still listening to whatever station it was tuned to but when it's doing this you can't change to another station. Today, each time we tried to change the station, it ejected a CD. And when we pushed the CD eject button, it turned itself off. Finally we gave up, turned it off, waited about 10 mins for the air conditioning to cool off the interior and then turned it back on again. It was perfectly fine at that point.

This has been happening more and more frequently. Usually the problem goes away when the car cools off.
Is there any hope for this radio? Or is it time to give up and replace it?

 

Just for grins, I went out to a local auto hi-fi company and priced out an aftermarket system with satellite, bluetooth (and even a backup camera). They quoted me $1200. That's insane.

I noticed they listed separate charges for things like the satellite tuner ($100 + $100 for installation) and steering wheel controls ($100). But mine still work, can't I use the ones I already have?

I'd prefer not to buy a used unit because I have no guarantee it won't be on it's last legs just like mine.

So the question is, if I want a new radio, how many things do I need to replace if I keep the same form factor (single DIN I assume) and assuming I do not bother to add a backup camera? I still do want the satellite and bluetooth capability as well as the steering wheel controls.
