Query: Altec Lansing IM510 Speaker System

Difficult to use when coordinating two pieces of electronics. The Sansa 250e did not play when plugged in to the unit. When I contacted Altec about the problem, I got a surly tech person, after the innumerable phone button presses, who told me, in barely intelligable English, I should update software on the Sansa 250e. I contacted the pleasant and helpful people at Sansa and did indeed upgrade the software successfully and am able to play the unit over the Altec speaker system. Since my experience with Altec, I do not expect that I will be seeking out Altec products anytime in the future, near or distant.
