THNAKS for the reply !! I checked the firmware in both units and they are 2.78 which shows on the web site as being current. I just purchased the units about 6 weeks ago. I also opened both units and checked the straps/jumpers again for the third time to make sure they are installed properly. I only had to change 3 of them when going from the 706 to the 7100 and I also did ohm them this time to make sure there was no broken ones. When I had them open this time I did see there is a RES button on them ...
should the unit be reset after I made these changes for the 7100 I did try operating the radio again and still only have the same ... I can only turn the unit ON & OFF .. I have no control or audio.
