I noticed that one at the bottom of the page when I was cut & pasting one of the other links. But looking at it again, I might have misled you... I think it receives Pandora via satellite - not internet.
I've used Pandora on my phone through the house WiFi... You sign up, it plays songs, you give a thumbs up or down, it quickly learns what music you like. You can pay to have no ads, but the free version only has short ads. It's still less of pain than the screaming infantile adverts on commercial radio.
So if you already have a phone and the data to spare, you could fit a single DIN head unit with bluetooth. Then stream Pandora (or mp3 files) from your phone. I believe you can leave the phone in your pocket, and change songs from the stereo. What I'm getting at is, you'd probably find you wouldn't use the tape deck much then. Especially if using something like Pandora (there's one or two others I think).
I like my tape deck too - it's hardly been used. But I plan to convert tapes/LPs to digital one day. I wish 240s had had a 2-DIN slot! I can MAKE it into one - if only I could figure out a way/where to move the aircon vents. I don't want to ruin the car, but at the same time, would love a larger-screen Android/stereo/DVD/GPS/Bluetooth/reversing camera - LOL!
If only I could get this but with Android instead of Windows:

You've probably already thought of it, but if you want to keep it original, some people fit stereos in the glove box, under the seat, up under the dash... Some different options in those links anyway.
