Anyone have a problem with their unit not completely starting up. Went out this morning and the radio came on fine. After a quick stop at a store, the unit started normally (Smart logo and name) but turned off before Starting to play the radio. The unit when thru this start-up shutdown cycle about 5 times before staying off. I initiated turning it in a few times but only got the same cycling. A few weeks ago while playing a CD, it shut off, when thru the restart cycling a few times, then finally resumed playing where it left off. Any clues? Any solutions???? Thanks!!!!!
