Time y'all west of the Atlantic switched to GSM(-compatible)
phones...problem described wouldn't be quote so bad.
Anyway, as Wolfgang reported earlier, a universal interface is now available
in Europe. Maybe will be fine for North America, too.
Actually I remember something peculiar about what was offered when in 2000 I
was ordering my car on Germany for import into the UK. UK dealers were not
offering the factory-fitted kit without a phone, whereas the spec/price list
in Germany (for cars to German and other specs) already offered the cradle
only version. Within months policy changed here in Britain, possibly
because hundreds of Mercs were being brought in as personal imports and
awareness of the ex-Stuttgart price list was high.
Forcing people to buy a handset with the car was decidely cussed, especially
if buying the phone without a contract (higher, unsubsidised price). I also
remember a fixed phone being offered in the UK, i.e. wired to the car. I
got away from that 10 years ago, or was that even longer ago?
You wonder what goes on in marketing men's minds sometimes.
NB: To reply directly replace "nospam" with "schmetterling"
