  1. Dash cam and few other bits

    A week into my Smart ownership, I've added a few things. Driving in Leeds city, the standard of roadmanship gives me cause for concern. Hence cheapie dashcam. I hate wires of any kind on display so hardwired to free constant supply on side of fuse box. Took off the plastic trim and ran cable...

  3. Need to replace Highline audio unit

    The Highline audio/satnav unit in my 2012 fortwo Cabrio (84) is not fit for purpose. Radio reception is poor, satnav capability is unacceptable. There are loads of double DNS units on ebay from less that £100 to £500. Has anyone here replaced their Highline unit? Can anyone recommend a decent...

  4. Remap a MHD?

    I wanted to find out if you can remap a 451 mhd. I am happy with the car but it does lack power. I am used to remapped 450. A respected company in North London offers a mhd remap for £175. Another respected independent told me you cannot remap a mhd. Which is right?

  5. Question Adding DRL - What is the big issue ?

    Iím told by Mercedes and a few independent Smart mechanics that the original DRL donít always work if retro fitted; even if a code is used. Apparently you can't even order it as parts from SMART to retro fit anymore, which seems bizarre. Given that the genuine lights as a retro fit are expensive,...

  6. Better Pollen filter

    Hi, anyone know of a better pollen filter or cabin air filter. I was kinda hoping there would be a company that made better ones a bit like K&N do for engine air filters but there is nothing I can find. Cheers Si

  9. Door speakers

    I want to upgrade the door speakers. Can it be done by popping off the grill & changing them over or do you have to remove the door panel everytime? I'm not wanting to go mad, was thinking maybe Kenwood 3-way speakers.

  11. USB power increase

Usual problem, the power from the USB is tiny and barely keeps the phone charged. One idea I had...and...

  12. Mpg

    I just filled up the wifes 2009 451 84Bhp (50,000 miles) today after the first couple of hundred miles mixed motorway/urban. I was surprised that it does less to the gallon than my Insignia achieving only 41.8mpg - especially as she has a light throttle foot. How do people manage to get the...

    Thinking of buying a set of front seat covers for the Fortwo described in my signature. It has both Bodypanels and Tridion cell in Silver metallic. I can get them in Black, Grey, Blue, Red, Green and Navy. I was thinking Grey would be the obvious choice but perhaps Black would hide dirt...

  16. Changing the head unit in a 451

    I was thinking of changing the smart sat nav for a different double din head unit and wondered if I needed a new facia for it? I thought I might try out one of the apple CarPlay units now on the market.

  17. Plasti Dipping my wheels

    So I got the itch to change the colour or my wheel, but didn't like the idea of painting/powder coating them as its a real pain to go back to the original polished alloy. So I decided to have a go at Plasti dipping them instead. For those who don't know what this process is, its just like painting...

  19. Improving suspension on 2010 Passion...

    Hi, I just picked up a 2010 Smart Passion to keep my Roadster company. I got a couple of questions. The main one is that the suspension is hard, and it is bonejarringly uncomfortable even when hitting a small pothole. The car's done less than 20k miles, so I'd assume the suspension is OK. I...
