An online automotive trade publication says that HD Radio is poised to become a factor in the OEM auto electronics sector. Autotech Daily, an online publication of Hampton Auto Beat, cites a number of press releases from retailers like Radio Shack and industry groups like the HD Digital Radio Alliance as indicators that HD Radio has reached the point where carmakers ought to be taking notice.

Analog Radio Sunset Begins in UK
Radio listeners in Great Britain will have a tougher time replacing worn-out analog radios, as leading online electronics retailer Dixon''s will no longer stock analog-only AM/FM radios.
But Curry's, Dixon''s parent company that maintains brick-and-mortar outlets in England''s major cities, will continue to offer analog radios at its walk-in outlets--at least for now.
The move by Dixon''s is a response to a tremendous growth in sales of DAB receivers over the last three years. A Dixon''s spokesman estimated that its digital sets are outselling its analog radios by a ratio of about 30:1. That observation reflects a significant up-tick from a 2005 report by British telecommunications agency Ofcom that reported DAB devices accounted for 54 percent of sales of all portable radio''s in 2005, up from 45 percent the previous year.
Dixon''s will continue to sell analog sets at its remaining tax-free airport stores and its shops in the Republic of Ireland where demand for them remains viable. The retailer added that personal CD players and boom boxes were also on the endangered list following the rise in popularity of Ipods and other MP3 players.
Radio Shack to Push HD Radio in NYC
Radio Shack is expanding a roll-out of HD Radio receivers in about 250 of the company''s nearly 350 stores in the greater New York metropolitan area.
The move follows in the wake of a May announcement that the consumer electronics giant was commencing a tiered introduction of digital radio product in its outlets nationwide. The first phase included all Radio Shack stores in Dallas/Fort Worth and less than 20 pilot stores in such markets as New York City, Los Angeles, Chicago, Philadelphia, Houston and Washington, D.C. Radio Shack claims the current push in metro New York is in response to increasing customer demand for digital radio receivers spurred by growth in HD Radio content offered in that market.
“The best way to interest customers in HD Radio is to allow them to listen to it in stores, see the type of information that is shown on the receiver''s display device and allow them to talk to knowledgeable, helpful sales associates who can actually answer their questions," said Wes Lowzinski, Radio Shack''s senior vice president, general merchandise manager. “That type of interactive engagement has Radio Shack stamped all over it. That's what we do better than anyone else."
Radio Shack is currently offering New York customers the desktop Boston Acoustics Recepter HD digital radio in stores and online for $299.99, with plans to offer additional models in the months ahead. Customers will be exposed to in-store, online and point-of-purchase educational support backed with an on-air promotional campaign airing on HD Digital Radio Alliance-member stations HD1 and HD2 channels.
