John, What do you mean by staying connected. Do you mean losing the blue-tooth connectivity between your mPower and the GPS receiver, or do you mean keeping a fix on the satellites? ----- Original Message ----- From: "john Harden" <john.harden@xxxxxxxxxxxxx> To: "gps-talkusers-freelists.org" <gps-talkusers@xxxxxxxxxxxxx> Sent: Saturday, June 21, 2008 2:18 PM Subject: [gps-talkusers] Holux M-1000 I had the older Holux receiver and was having a problem with the mPower staying connected to it while walking. It worked well while on the bus ETC. I got a new M-100 and I get a whole lot better accuracy and it connects and gets a fix a lot quicker but while walking it still won't stay connected. I am not walking in an area where there are a lot of tall buildings and we have more clear skys than in most areas. I wear the equipment with the receiver on my right shoulder and the mPower on my left hip. Do you have any idea what might be going on?
