Sup guys, I was looking all over the forum about aftermarket radios and things about losing functions like mileage, temps, service dates, etc. I don't know anything about aftermarket radios bc I never wanted to changed them on my previous cars.
so my question is what are the things I need to buy in order to not lose these functions (yes, I checked other threads and clicked on the links. The links are not working anymore, so no need for any dumb comments
)
Another question is, has anybody installed a Sony XAV-AX100? Looks really good compared to the stock hu in my e92.
