Thanks. I got the Nuvi updated but I had to use IE because firefox wouldn't run the download manager. I didn't realize that that City Navigator would get loaded into Mapsource.

I recently purchased a Nuvi 255 and wanted to know if there were any issues with connecting it to my PC that already has Mapsource installed that was used to download Gpsfiledepot topo maps to my 60csx. I want to get the free map update for the Nuvi255. Does it use Mapsource or some other method for the upgrade? Thanks, jmak

Requested MediaTek sensitivity link http://www.gpspassion.com/fr/articles.asp?id=258 MediaTek news release http://www.mediatek.com/en/news/info.php?sn=15

Thanks for the replies and links. Although the links are interesting I think a side by side test of the different 60csx models would be a more realistic apples to apples comparison. I took my Mediatek version out for a walk today on a hilly ATV trail under fairly thick canopy. I walked for half a mile and retraced part of my track back to the house. The two tracks matched fairly well, deviating by at most 12 feet. This unit is light years ahead of my old Meridian Gold unit. I am leaning towards keeping it.

The new 60csx are using the MediaTek MT3329 chip that is advertised as being more sensitive than the SiRF chip. The results of a side by side test under heavy canopy would be interesting.

I just received mine from Amazon and it has the MediaTek chip in it. Software Version 4.00 GPS SW Version 2.00m

I am interested and sent you an email.
