First post here... Found this thread by searching for my HU, and looking to see about adding waypoints...
So, I thought I'd throw out some good info that might help others;
I've bought a refurb'd unit... for $900, and have updated everything (firmware, bluetooth, GPS Maps...etc) and have had NO problems with anything since those updates.
... the bluetooth used to drop after each call ended. Doesn't do that any longer, and works perfect (with a Motorola Droid) especially after adjusting the mic volume to 4, and placing it directly in front of me (steering column or at visor area)
... the mapping, used to not show roads/street names too well... and with the update, it's helped. Shows me what I need (in my opinion), and is FAR superior to an Alpine (INA-W900)!! Plus, I was able to upload my own POIs for red light cameras, personal waypoints as POIs...etc.etc. with (proximity) alerts!
... I was able to upload my own splash screen. Very cool and custom feature.
XM, Traffic, iPod....etc all work great, and I've not had any problems. Even with this refurb unit... I bought a 3yr warranty, and hadn't had to use any of it. I'm thoroughly pleased, as this unit replaced my B Pillar mounted Garmin Street Pilot 7500 unit.
If it helps, here's a link to the install (at ford-trucks dot com);
