Im not the only one on here that has had the satnav navigation joystick stop working .
well there is a cure for it . price wise its cheap cheaper than a second hand unit . price of repair approx £10
the hardest thing is getting the correct joystick . I contacted the circuit manufactures who gave me a company in america who sells the correct part . I have 2 SPARES for the first 2 people who want them £10 each . i can get more but would like if possible just to do one mass order so that there is just one fedex postage charge .
plus a steady hand + soldering iron + and desoldering pump . a pair of snipe nose pliers or similar will be helpful also .
I must state that if you cannot solder /desolder please dont attempt this as you could render the whole circuit useless if you damage the tracks when desoldering
in this case get /pay some one to do it for you it will still be a cheap repair .
Firstly remove the centre console plastics starting with the cup holder by tugging upwards on them sharply
after removing the gearstick plastic grab the bottom of the nav/aircon surround at the bottom and pull forward ,this is just clipped in like the rest .
carefully tilt it over and remove the 7 electrical connectors from the back .
once you have removed the connectors take the console to were you will be soldering . remove the enter button and the two audio buttons by pulling sharply off then turn the unit upside down protecting the painted front .
you need to then remove the 8 screws around the white plastic unit in the centre of the console and lift it out .
carefully lift the circuit board out with the connector socket thats onboard
now we have to desolder the switch
This is the ackward bit i used a soldering station and a desoldering pump but due to the solder passing through the board i still ended up cutting every pin off the switch and removing each pin individually ,took me around 20 mins really didnt want to damage a track and then have to repair those also.
when done it should end up something like this ,the mess around it is just flux from the solder nothing to worry about
nows the time to solder in the new switch !! It can only fit one way as it has 2 locating lugs on the bottom which fit into the circuit board .
solder up all the pins on the reverse of the board and reassemble the whole unit . if youve done this correctly once refitted in the car i guarantee you will have a 100% working navigation which feels better than ever .
heres a pic of the new switch fitted before reassemblly
