Dave,
Thanks for the great feedback on iFly Streets.  As for the DC cord, we are looking at options for a new style DC cord.  Maybe coiled, maybe with a on/off switch on the Cig end.  I've even had the thought of sourcing a plug that had a mini emergency battery or super capacitor built into it.  So if the plug came out or power failed, you might have few minutes to resolve or land.  Just a few options and most definately something to look into.  Keep any eye out as we are always looking at ways to improve and accelerate the iFly GPS.  Have a great weekend and Happy Holidays!
