HNR - HSP - TMC - TMC PRO - With or without it???

I hope I am not opening post that has already been open but I would really like to learn more from you guys, from more experienced users or drivers.

TWO BIG Qs

- Simply how do you fully utilize HNR, HSP, TMC, TMC PRO (not clear what this is) etc?
- Is there a big difference in routing when HNR, HSP files are present or not?

This is what I found on line and if somebody can provide us with more info (simple) please do it.

TMC (Traffic Message Channel) in Car GPS Navigation Player System



TMC (Traffic Message Channel) in navigation function is a technology for delivering traffic and travel information to motor vehicle drivers. It is digitally coded, using the Radio Data System on conventional FM radio broadcasts in car DVD player. It can also be transmitted on Digital Audio Broadcasting or satellite radio. TMC in gps allows silent delivery of dynamic information suitable for reproduction or display in the user's language without interrupting audio broadcast services. Both public and commercial services are operational in many countries. When data is integrated directly into a navigation system, traffic information can be used in the system's route calculation.
