What is the warranty on the Directed Electronics automotive add-on tuner unit? Less than 2 years of operation, and now when I power up my HD tuner it will show the preset frequencies with full-scale signal strength for all of them; but no audio, no HD decode, no analog audio; nothing - just a frequency - both AM & FM. The built-in FM modulator does kick in after 5 seconds, but that's it. I've tried cycling power, removing the memory connection and power connection, reconnecting the remote display/operating head, and nothing changes. Pretty upset as it was a huge pain to install, tearing apart half the dash to get to the antenna connectors in the A pillar, etc. Does anybody else have one of these useless Directed Electronics mobile HD boxes? Does yours still work - if so, is it the metal tuner case or plug-in remote unit that bites the dust? Anybody have any 'donor' parts or should I just forget it? I liked it for the RDS and narrow selectivity on FM, but that's pretty much it. Damn - what a pain to install - if nobody has any suggestions, I'm just going to rip it out this weekend and build a female to female antenna jumper cord and put that in it's place. What a shame - not even two years of use! Maybe the radio got a signal from Cidatel that they're Chapter 11 and not going to have to pay iBiquity their fees anymore? Anybody have a decent contact at Directed Electronics?
