"Free Lifetime Map Updates" Policy

Free Lifetime  Map Updates for any CMNAV Sat Nav purchased from the website

Update Process:


Usually, map updates are released 1-2 times per year, but keep in mind that this is not a rule. There is no fixed date for updates release, therefore we cannot announce to you exactly when these will be available.

Also, it takes a few weeks from the moment when the first updated content was released, and they will keep coming every day until the update is complete and ready to use (For example some maps are released today, but it might take 2-3 weeks until the rest of the maps will be added and other content such as speed cameras or points of interest).

So we cannot release the update pack until all of the maps and content are available! Installing an incomplete update pack might cause errors and we don't want this. 

The best way to find out about this will be by contacting us via email at, inquiring about updates, or by using any other contact method available on our website. 

Please provide us with the order number, or, if you don't know this information, please attach a picture of the invoice included in the box to that email so that we can identify the transaction date and the sat nav model, check if there's an update available after the date you purchased the sat nav and also, make sure we send you the right files for your sat nav model. 

The invoice is physically included in the box with the item but it will also be emailed to you at the moment when you place the order, so you should have it in electronic format, but in case you did not provide a valid email address it is very important to keep the paper invoice safe or take a picture of it and keep it somewhere on your phone/computer for further updates, in case you cannot find the order number.

Please note that pictures of the sat nav won't be considered proof of purchase.

Screenshots of bank transactions will not be accepted either, unfortunately, as there is nowhere stated Sat Nav model.

After providing proof of purchase and the order is verified, you will receive a video tutorial where the whole update process is explained step by step, alongside a download link for the latest maps, so that anyone can do it, regardless of their computer skills level.


  1. Access to a computer/laptop (preferably running on  Microsoft Windows Operating System - we can't guarantee that macOS from Apple or any other Operating System would work)
  2. A stable, decent internet connection (you can use your  mobile data allowance too, but please check with your provider as this might incur additional costs and charges if you exceed the monthly limit or breach their download policy)
  3. A nice cup of tea or coffee and a couple of spare hours (usually) 


Not having access to a computer or internet connection will lead to the impossibility of performing the map update. 

In this case, we can still help you update your device, but this will not come free of charge. You can send the device back to us at your expense for both sending and returning device postage - we will send prepaid labels (printer required) or you can pay directly at the post office when you send the sat nav. 

If you'd like us to update your device, the cost for that will be £25 and this includes the price to post the sat nav from us back to you.

Any unreasonable demands, failing to provide proof of purchase with the device model on it, will be politely declined.

Also, please be aware that our updates are not compatible with other devices and using these on other devices than CMNAV sat navs may lead to permanent damage to that specific device and we are not responsible for that.

For any other questions, feel free to use the big Help Button on the bottom right corner and select one of the contact methods you prefer from that list.
We normally aim to reply within 30 mins, but even if we won't be reachable at the time, we will get back to you, no matter what! 

Disclaimer: C & M Navigation Systems reserves the right to refuse or cease providing Lifetime Map Updates without notice at any time in case there are suspicious activities from the user requesting these ( e.g: A potential competitor attempting to copy our work to be used for their interest).

Free Lifetime Map Updates means that you will be provided with relevant map updates for the type/model of device you have purchased until the model/product is discontinued or until C & M Navigation Systems cease trading on the market. This decision will be communicated to our customers at the time when they will inquire about map updates if this is the case.
