Given how "in the dark" you are w/ respect to your wife's devices, passwords, etc, I'd probably start w/ a VAR. I wouldn't worry about the radio; if she's talking on the phone, she'll turn it down. And unless she's driving for hours at a time, it shouldn't really fill up. That said, some of the Sony VARs do support micro SD cards for memory expansion.
Be sure to read @weightlifter
's "Standard Evidence Post" thread here in CWI for tips regarding VAR configuration and placement (Pro tip: use lithium batteries and lots of Velcro.)
Casually mention bundling your different ATT accounts in order to gauge your wife's reaction.
Have you mentioned marriage counseling to your wife? If not, do that, making sure to mention your dissatisfaction w/ what seems to be her rather perfunctory commitment to your sex life, and take note of her reaction.
Don't mention the ATT account bundling and MC within the same conversation. In fact, I'd probably wait at least 2-3 days after mentioning one before bringing up the other.
Maybe mention the account bundling after spending some time paying bills, or looking into a new phone for yourself, etc, so that the conversation seems organic. Along the same lines, maybe wait to mention MC until the day after
the next time you have sex.
When your wife gave her old phone to your son, did she factory reset it first or did she just delete a bunch of stuff? Does he have his own iTunes/iCloud account, or does he have his own? Does he use the old phone as an iPod/media device, or does he use it as a phone? If you don't know the answer to these questions, DON'T ASK HER. Hell... don't ask him, either.
What kind of cell phone do YOU use?
What do you do for a living?
On a scale of 1 to 10, how tech savvy would you say you are? How about your wife?
