Has anyone seen any comparison of these two systems? The price difference is only $60 but one of them (Prestigious Society product) apparently loses the map while the bypass system is activated and regains it once the system is deactivated. Not a deal killer but something of which you should be aware.

I want to have such a system installed on our newest Lexus and seek the collective wisdom of this group as to which product is best.

I will gladly stand corrected if Beat Sonic found a way to keep the map updated (even though you're not looking at the map while watching a DVD).
