Highline Stereo Hacking
The Highline stereo would be a much better unit if it wasn't for the terrible sat nav software.
The idea is to personalise the unit and force it to use a better navi program.
Highline Stereo Retrofit
So, you bought a Bosch Highline touch screen stereo and want to fit it to your car?
As long as you have a smart that can accommodate a double DIN stereo, you are in luck.
Highline Swap Out

How To Clean Your Windows
You thought that moving some dirty water over the windscreen using an old pair of holed underpants was ok? Although that may get rid of some bird shit and the worst of the road grime, the glass isn't clean. Dirty glass collects more dirt as the new sticks to the old....

Hyper Reclining 450 Seats
The 450 drivers seat reclines enough for every day driving but not enough if you want to have a sleep. Do not do this modification and drive around with the seat reclined right back. This is about the maximum that the back will move to as standard. Ain't no one...

You can already buy this type of device for about £20 which is a bit of a rip off considering the value of the parts doesn't exceed a quid.
Ignition Key Will Not Turn
The Key Won't Turn Because of the position of the ignition hole on the 450, 451 and Roadster, it's very common for them to get full of shit like dust, cake, sugar, fur, crumbs, bogies, chocolate, finger nails etc. The ignition barrel isn't open underneath so anything...
