How do I reset my magellan roadmate 760?

Hi,
Your magellan roadmate 760 unit does not have any reset option.To over come the signal problem just follow the trobleshooting steps givven below .............

NOTE: If you are trying these steps from your vehicle, it is
Recommended to follow when the vehicle is in a stationary position.
Make sure that the device is exposed to the clear view of sky.

With the antenna pointing upwards, remove the antenna and then re-insert.
Swivel it up and down to make sure its securely placed.
wait for few mins and check the signal indicator.
Still not working,

• Turn on the unit and select any user.
  
• Make sure that the antenna is in the upright position and the unit has
  a direct line of sight with the sky.
  
• Select 'Option' from the keypad.
  
• Then select 'Configuration'.
  
• Scroll down to select 'Diagnostics'.
  
• Scroll down again to select 'Initialize GPS'.
  
• At this point you would receive two options, 'Yes or No' - select 'YES'.
  
• Now scroll down and select 'Set GPS Position'.
  
• Enter your City, Street name and number at the corresponding
  prompts.
  

I had the same issue. i ended up buying a garmin nuvi 680 as i needed something immediately. months later i plugged the gps into my pc and ran diskcheck. no problems found. i then ran acronis truimage echo workstation and imaged the gps to a file on my hard drive. i pressed - and repeat at the same time on the gps whe nit booted to the select user screen. i went to the utility to format the drive. upon reformatting the drive i restored the image to the gps via usb cable in acronis. took about 4 hours to do this since its usb 1.0, but the end result upon rebooting the gps was that in 5 minutes it locked onto my location.

Does this do anything? It seems like setting the position is an override, and doesn't help the GPS locate anything.
