Yep, the maps are the same. When I purchased my mPower from Sendero, I only had to purchase a second license for the GPS to run on that unit. For, I had already purchased the maps and the receiver for use with my PK, and those work just fine with my mPower as well.

I am having problems logging in on the mysendero web site. I am only going to download maps so are the maps different for the pk than for the mpower? I was using the pk serial number but I can use either the voice Note or Braille Note mpower's serial numbers if the maps are the same. I really want to start on this project today because I will be getting ready to travel East on Wednesday. Thanks for your help. Mary Ellen Earls
