Hi Sendero staff, Currently, I am fortunate enough to own both a PK and a mPower. But not fortunate enough to pay for the GPS upgrade on both machines. Do you forsee any significant feature differences between those two models? Humanware seems to have fewer and fewer features implemented on the PK these days; kind of like how the classic model has experienced. I just paid to transfer my GPS from the PK to mPower, but it's been kind of bulky to carry it around. If there will be no significant differences between those 2, I will consider switching back to the PK. Thanks. Koji -------------------------------------- Enjoy MLB with MAJOR.JP!
