I'm back!
The patch seemed to do the trick! Thanks for the reminder.
Can hardly wait to get out on my bike again to test the map more thoroughly.

No, I have not installed the patch. Am downloading it as I type. Had forgotten about it.
I did try a larger swath the first time, with the same results.
Thanks for your help & suggestions.

Coordinate example:  N38 00.724  W 121 22.110  to N38 00.011 W 121 21.478
This defines a region that includes my neighborhood.  The streets/roads are missing beyond this region to the east and north (and west?).
I noticed that this seems to be one segment of the whole that I thought I had selected. Roads show further south just fine, and accuracy is good. 
(Later) I just simplified my selection in MapSource, selecting only one "block" defined by (top left) N38 09.248  W 122 00.497 to (lower right) N 37 00.689  W 119 58.630 ... downloaded to my GPSr and got the same results ... no roads above about N38, roads below N38.

Thanks for your help and suggestions.

I just discovered GPSFileDepot and have downloaded the US map. From it I selected a small portion around my home. My question is this. The map, when viewed on my computer monitor, shows essentially all the roads in my neighborhood, but when I have selected the portion I want and downloaded it to my GPSr many of the roads do not show up on the GPSr display at any resolution. Why is that? They are not new roads in any sense of the word since this whole area/neighborhood has been around for over 30 years. 
The map, where the roads do show, seems to be much more accurate than the Garmin topo map, but if key roads are totally missing accuracy is not the issue.
Thanks for any input. Perhaps I have done something wrong and the road data has been lost in the process.
