Help! I'm planning to compete in the Silver State Classic Challenge in May. This is a timed rally event in which drivers attempt to set a specified average speed (105mph in my case) across a 90 mile stretch of road that has been closed for the event by the Nevada State Police. Details are available on http://www.silverstateclassic.com

I will mainly be relying on my copilot/navigator to manually time us by mileposts and other markers, but I'm thinking of buying my first GPS too. I'd rather spend under $300 for a handheld unit like the Garmin Legend C, but I'm unsure whether it will map Nevada Highway 318 from Lund to nearly Ash Springs.

Can anyone with a handheld sub-$300 GPS let me know if their unit has this highway?

Thanks in advance,
Simon
