Garmin Nuvi Won't Switch On

Panic stations everyone! The Sat-Nav is not switching on!!

Good job I was at home and only had to find the location of a birthday party my son had been invited to.  The combination of google maps and my memory got him to the party...  Just.

So, what the.... happened to the sat-nav?
  
Luckily there is a simple enough fix.  To get the unit functioning again you have to perform a 'soft reset'.  Here's how:

• Connect the sat-nav to a PC via USB cable
• Push and hold the power on slider to the on position and hold for 10 to 15 seconds
• Release the power on slider
• Try to power sat-nav on as usual.  The unit should switch on as normal
• Unplug USB cable and you're good to go

Phew!

As recommended by the Garmin article, I updated my unit to the latest firmware and software versions.  As I've just experienced a 'bricked' sat-nav, I performed the updates one at a time.

The updates I applied and the versions my unit is now running with (for comparison) are as follows:

• Chipset firmware / software = 4.80
• Traffic receiver firmware = 5.50 (will only display and update when the unit is powered via the car cradle)
• Audio software = 1.60
• GPS software = 2.90m

I also updated the British 'Emily' and 'Daniel' text to speech voices in the hope they can better pronounce some of the more obscure place names around sunny Kent.
