The whole digital aspect of vehicles is a scam of HUGE proportions.
Just to plug in the cable is (locally) 75 bucks. For ANY update/mod/reset etc. it's an additional 100 UP.
When my radio/CD for the '01 V70 died, I installed a re-man. The dash lights for it wouldn't come on. The ECM had panicked (Alert, Alert!. Foriegn component!!!). The radio/CD worked but the dash lights and LCD back-lights didn't work so, essentially the thing was useless as far as my wife was concerned.
The car also had steering wheel mounted controls for volume and "Mode", which also didn't work, but I didn't care about that since when they DID work (don't know why they originally quit), I constantly hit them (changing stations, whatever) with my hand just by steering.
Anyway, it cost me $200 (and about 5 minutes) for the
Volvo Dealer (NOBODY else could do it) to download whatever miniscule data that was needed to make it work. Of course, now the wheel controls work again as well and I'm back to old unexpected radio changes.

And don't get me started on how "OnStar" and the like can be (and have been) hacked. That is
scary...

I still own one
analog car. Sure, the mileage sucks, but I can start it, if need be, by pushing it... and nobody knows that I'm on the road.
