I've been a lurker in these forums for a couple of weeks since I purchased my cappy. Thank you everyone for your insight, suggestions, work-arounds, etc. I too experienced major problems with GPS navigation, lock-ons, etc. I tried every work-around listed in these forums and though most of them work, they only work temporarily! I have a work-around that works for me every time. When I fire up Navigation, my cappy refuses to lock on (like many others), or when it does, it fails shortly after. Keeping the navigation running, I hit the home key, go back to dialer, type *#*#1472365#*#* then click the "Get Position Test. Within 10 seconds, I'm locked onto 10-11 sats, then switch back to Navigation and my GPS is now locked on and works perfectly for the duration of the cross-country trip. It appears to me that firing up lbsTestMode creates the necessary "link" data for the other GPS software programs to function properly. This work-around has worked 100% for me on my last 10 car trips. Can everyone else try this to see if it works for them?
