Dont simply assume the Procede flash will solve your problems. I thought the same and when the flash came back I had new problems that Vishnu refused to acknowledge.
Wouldn't return my phone calls or emails. Its been 2 months and I'm still waiting on my "Guaranteed he will get to you this time" reply from Shiv himself.
If you don't live near them I would stay away from the flash option. It is impossible to get any help otherwise, even when they make a mistake.
My car is now totaled (thanks to a dump truck losing its cargo on the interstate) so my muffed DME is in the junkyard where it now belongs.
