I just had the original radio in my RAV4 Limited replaced under warranty. I hadn't noticed any reception problems (maybe because I didn't know what I might have been missing). But the display started cutting in and out, or showing weird, alien characters and sometimes the radio wouldn't turn on or wouldn't turn off. The new one actually seems to sound better to my non-audiophile ears than the original one.

Reception seems OK, but if there's something I should be getting and I'm not, how would I know?
