Navman MiVue 155 Safety

Navman MiVue 155 Safety Dash Cam is a bit deficient – I had a Navman 540 dash cam for several years and it worked OK. I know that Choice magazine doesn't recommend any dash cam as all of the ones that they've tested to date have poor night time performance. I had enough Telstra points and so I got a Navman MiVue 155 Safety mode for free. I know that I pay for it in my telephone bills and that nothing is really 'free' these days. So I updated and have installed the 155. There is no instruction manual, as is so often the case. You have to download a pdf file is you want to read the owner manual. It is on a par with the 540 model, but with a few added features, a wider screen and two menu pages with easy to understand control buttons. To date, the image quality is OK. My main beef with the 155 is that Navman have obviously cut costs (Ha! I got it for nix) by having a primitive mounting system, that is very stiff to move and seems to be a permanent mount on the windscreen. While you can remove the camera from the mount, you cannot remove the mount from the windscreen as it is mounted using an adhesive electrostatic plastic sheet and adhesive pads at the base of the camera mount, that stick to the plastic sheet. At least the 540 had a suction mount with an easily moveable mounting gimbal system. While it often fell off when the temperature inside the car was too hot, I got around that problem by using a 3M adhesive plastic disc. At least Navman haven't changed the cable. so that I have kept my old one in place. A good thing is that with the 155 you get a 32Gb mini SC card, which is something I didn't get when I bought the 540. If only the 155 fitted the 540 mounting system, but I tried and it doesn't, which is a shame.
