I've had "support" experience over the last few years with Magellan,
Garmin and recently TomTom.

Magellan took ages to tell me to get lost.

Garmin was helpful and competent.

With TomTom, daughter wanted an urgent Satnav for someone who was an
on-your-bike you quango-site government victim. It had to have Homer
Simpson as the voice.
Research showed this had to be a TomTom, so I got one (Halfords (spit)
with a bait and switch European maps offer, but that's another story),
got it home and rang support to find out how to purchase and do the
voice change without getting the unit registered to me rather than the
recipient.
The English-sounding rep hand held me through the whole process and
de-registered me at the end. Inevitably, something went wrong, probably
at my end, so he logged it as a fault and cancelled the charge for the
extra voice.
I have to say that I was really surprised and impressed.

SWMBO and I did one short trial run with Homer. Not sure about the long
term, but our little trip was really fun.
