Gamin's Nuvi 5000 was primarily aimed at the US SUV and truck cab markets.

Has all the options i wanted, and after much searching managed to pick one up, BNIB, but very old stock.



Plugged it in, got free update from the installed 2009

maps to current FOC.

Also picked up a 2nd one as a spare off ebay.com.

Then spent a whole evening designing and uploading a boot screen, and learned how to dismantle the unit to remove the front bezel:



Got hold of external GPS receiver and external speaker.

The original dash panel was a bit pants from the outset:



And was never going to cater for my plans.

So i had a new one made in autoclaved, pre-preg carbon.

1.5mm thick and weighs less than 100g.

Not cheap at

£300 but exactly what i wanted.



So now to design the layout.

I didn't want any toggle or rocker switches, so decided on momentary push button switches.

Large internally illuminated for main circuits, and smaller ones for dash programming.

Using resistors and diodes, the illumination of each switch will have two levels, one for when lights are on, and a brighter one for when circuit is switched on.

Found a manufacturer of the switches in Canada.

More expensive than the Chinese copies on ebay, but worth the extra money.

Sorted a latching relay for each of the 5 main circuits:



Engine start button is courtesy of Silver Horse Racing in USA.

Made in the USA, and a Ford approved accessory:



A CarTek electronic battery master cut out switch and a Lifeline electrical extinguisher switch will complete the dash furniture.

The dash layout design was done in Photoshop.

Once happy, i reproduced the layout on graph paper.

The whole lot was sent off to the only carbon fibre specialists i will use, Reverie, for routing out.

As expected, the result is perfect:



The dash is going to be printed, so i had Reverie flat off the panel ready for printing.

To ensure no ill effects from the final lacquer reacting with the printing ink, several samples will be printed on a piece of waste carbon and sent to Reverie for lacquering.

Once i have the results, the dash will be printed.

Meanwhile, onto the design of the wiring.

This is going to invlove a complete rewiring of the dash loom.

The Noble spade plugs/sockets will be dumped in favour of Deutsch plugs, the standard plug in all forms of motorsport.

Two reasons: reliability and pin density.

Deutsch pins are individually machined, and use a special tool to create 4 crimps around the pin.

The only way to guarantee every crimp is perfect is to use the correct tool, so

£200 lighter, and here it is:



Plugs and pins have been ordered.

Off to see the printer later this week.
