Does Uniden America have influence on other divisions? Well, let me answer that question with another: Name a model that was not developed under Uniden America. (IOW, name a model that is available in places other than the USA)
The other divisions, if you will excuse the term, leech off the products developed under the America division. Now, I don't know if they then pick up the tab for the R&D costs, or reimburse a percentage, but certainly they are not leaders in scanner development.
I agree that Uniden Australia and other divisions are not as responsive to theie respective markets, but it cannot be the responsibility of Uniden America to support the entire world unless Uniden changes their structure.
All this said, if Uniden America wants to develop a model that is not 'readily adaptable' to other markets, that is their right. It is not Uniden America's responsibility to provide products for other markets to sell. Other divisions can develop and market their own products, too.
Where is the Australian version of RadioReference? Has anyone in the scanner community started such a website? Who knows - maybe this product will either:
a) Encourage such a site to start, or
b) Encourage RR to expand to cover more of the world's areas.
If either case happened, the HP could be easily adaptable to other markets.
Of course, the Aussies could always join the states and start paying our taxes.

Actually, that would be a terrible idea for reasons I won't get into.

Joe, hate to break it to you but I beg to differ. I agree that there are limitations that Uniden US have but surely they influence other divisions of Uniden. Uniden Australia have not supported the Australian market. Not one firmware release since 1/2007, no sign of the XT range of radios and I daresay this one won't even get a look-in.
If Uniden Australia were to pick up this unit, it would be what we need. Trying to program the systems around here can be a nightmare even for experienced users.
