One of the key things that I needed from a New smartphone when I decided to move from Symbian was good satellite navigation. I looked at alternatives such as the Apple iPhone and it’s Satnav solutions, reading the reviews carefully, but unfortunately there didn’t seem to be anything that hit the mark and everything was a compromise. When I looked at HERE maps (or Nokia Maps as it was then), I didn’t have to make any major changes and it was something I was familiar with. When I bought the Lumia 820, I eventually settled on a Nokia car mount (the model escapes me – CP-115 I think) which I had to modify by cutting the rubber grip with a scalpel knife as it was such a tight squeeze. Other third party Satnav mounts never seemed to stick to the screen, so this worked for me for a good while.
Because the Lumia 830 has a 5 inch display, I would need a brand new mount. Thankfully the Microsoft / Nokia website has clear specifications which includes the dimensions of the device, I was able to compare this to the available jaw grip specs of the CP-123, which confirmed that it would do the job. So I ordered one for Christmas and tested it in the New Year once my Lumia 830 was back from being replaced due to the manufacturing fault.
The mount itself is huge – a large plastic arm with the sucker grip at one end and the phone holder at the end, connected via a universal joint. The phone holder clamps can be adjusted by moving the clip at the bottom of the holder, so that the phone is firmly held in place. There is one big disadvantage in using the CP-123 with a large Lumia phone such as the 830 or 820, is that one of the grips presses the camera shutter button. The only way I’ve found to get around this is to clamp the phone into place, the camera app starts, press backspace to exit it and then start HERE navigation and there isn’t any further problem. I tried different orientations including where the volume button gets pressed, but this was more than the phone could cope with so I went back to gripping the camera button instead.
To secure the mount in place, there is a lever which when pushed into place, clamps it to the windscreen – and it really does hold it into place. I’ve driven up and down side roads and motorways and the phone is reassuringly secure – no chance of it falling off the screen because the sucker loses grip. In addition, there is a tab on the rubber sucker to help the release of the mount from with windscreen.
There is a small hole where the MicroUSB charging cable can be plugged into the bottom of the phone (Lumia 820), in the centre phone clamp. A useful tip if you are using a Lumia phone for Satnav for any sort of distance navigation, is don’t bother with any of the third-party 12 volt chargers, such as ones designed for the iPhone, because they don’t provide a Lumia with enough charge to offset the discharge rate when using the phone for navigation. Typical third-party chargers only supply about half the one ampere needed to keep the phone topped up. I went through a number of these before I finally ended up with an Nokia DC-20 dual USB port charger (supplied with MicroUSB and 2mm coiled cables) which does the job perfectly. I bought my DC-20 from Amazon, as it doesn’t seem to be listed on the Microsoft / Nokia website.
I now have my perfect satnav system using my phone and my old TomTom PND has been retired to the bottom of the study drawer.
Overall, both the CP-123 and DC-20 are excellent products and well worth seeking out if you want to use your Lumia for satellite navigation.
