DISCLAIMER. I only googled this 5 minutes ago. I'd verify this but listening devices are legal in the UK IF it's a public place or your own home. I don't think your W's car falls into that category but I'm not an expert.
And people miss type their passwords all the time if you get my drift.
Quick thinking NDY.
Maybe the car is titled in his name?
Plus, what listening device? Buy it with cash and hide the receipt (you can usually return the device once it's done it's job....it's not healthy to keep snooping and you are more likely to get caught the longer you do it and it'll then become all about what a controlling, emotionally abusive, suspicious spouse you are - so return the device and get your cash back within the terms of the store you bought it from).
Practice with the device but when it's hidden it should not have your voice on it all all. If she finds it, it'll be hard to claim it wasn't you if the device has your voice on it. It's so easy to accidentally test it and say "HI" or "testing 1, 2 3". Delete any test recordings you make when practicing with it. This way you can deny it's yours. Maybe it was OM. Maybe it was your wife trying to set you up as a controlling overly suspicious snooper. Whatever, but it wasn't you.
BTW - I'm over a decade recovered. My wife is THRILLED with everything I did to save her and our family. Snooping is what's best for her too because she's been living this lie for a long time. It's like pulling off the band-aid...it'll be a relief to her to some extent (though that won't be obvious for a long time).
The internet is 90% complaining and entitlement and I hate it because I deserve better!
