For professional drivers across the UK, especially taxi and private hire operators, reliable navigation isn't just a convenience – it's the backbone of their livelihood. Google Maps has long been a go-to tool, but many encounter a peculiar quirk: the 'Preview' button appearing where the 'Start' button should be. This can be a source of frustration, leaving drivers wondering why they can't simply begin their journey. Thankfully, this isn't a glitch in your system but rather a feature of how Google Maps operates. Understanding this mechanism, and exploring the array of alternative navigation apps available, can significantly enhance your driving experience across Britain.

Imagine you've just picked up a fare, entered their destination into Google Maps, and are ready to go, only to find a 'Preview' button staring back at you instead of the expected 'Start'. This common scenario often leads to a moment of confusion. The simple truth is, Google Maps only displays the 'Start' button when your current location is either at the designated starting point (Point A) of your route or somewhere actively along the planned path. If your device's GPS indicates you're not yet 'on-route', the 'Start' button is replaced by 'Preview', allowing you to review the directions without actively navigating.
Your Current Location: The Missing Piece
The core reason for seeing 'Preview' is that Google Maps doesn't detect you at Point A. It's a matter of semantics – you can't truly 'start' a journey if you're not physically at the beginning of it. This isn't an error; it's the app's way of accurately reflecting your status. For instance, if you've planned a route from a specific address but are still a few streets away, or if you've mistakenly set Point A to somewhere other than 'Your location', the app will offer a preview until it senses you're at the correct starting point or actively moving along the route. Once it registers your movement along the intended path, the 'Start' button will automatically appear, and turn-by-turn navigation will commence.
How to Ensure Google Maps Shows 'Start'
There's no 'fix' for the 'Preview' button because it's working as intended. Instead, the solution lies in ensuring your settings and starting point are correctly configured. Here’s a breakdown of how to resolve this minor navigational hiccup:
1. Verify Your Starting Point
The first step is to double-check the text field at the top of the Google Maps directions screen, where you input your starting point (Point A). Ensure it clearly displays 'Your location'. It's surprisingly easy to accidentally type in a precise address for Point A instead of letting the app use your live geo-location. If you find a specific address listed there, simply delete it or tap on it to ensure 'Your location' is selected. Once this is corrected, and you are indeed at the starting point, the 'Start' button should become available.
2. Check Your Phone's Location Settings
If you're certain you're at the starting point or on the route, but still seeing 'Preview', the issue might be with your phone's location permissions. Software updates, particularly on Android devices, can sometimes reset these critical settings. Here’s how to check and adjust them:
- Navigate to your phone's 'Settings' menu. This is usually represented by a small 'cog' icon.
- Scroll down until you find 'Location'. It often has a green pin icon next to it.
- Ensure the main 'Location' toggle is switched 'On'. If it's greyed out, tap it to activate your phone's location services.
3. Review Google Maps App Permissions
Even if your general location settings are on, the Google Maps app itself might not have the necessary permissions. From within your 'Location' settings:
- Tap 'App permissions' or 'Location access for apps'.
- You'll see a list of all installed applications. Find 'Maps' (or 'Google Maps').
- Ensure Maps is listed under 'Allowed All The Time' or 'Allowed Only While In Use'. If it's under 'Denied', tap on 'Maps' and change its permission to one of the 'Allowed' options.
Once these checks are complete, Google Maps should accurately detect your position, and the 'Start' button will appear when you're ready to begin your journey.
Google Maps: A UK Taxi Driver's Trusted Companion or a Fair-Weather Friend?
For many years, Google Maps has been an indispensable tool for drivers across the UK, offering a user-friendly interface and robust features. Its ability to provide easy direction-finding, coupled with live traffic updates, makes it incredibly valuable for navigating busy city centres and motorways. Multilingual support and an incognito mode are additional benefits that cater to a diverse user base.
However, despite its popularity, Google Maps isn't without its limitations, particularly for professional drivers who rely on precise, uninterrupted navigation. One significant drawback is its minimal offline functionality. While you can download specific areas, offline use is often limited to basic driving routes, lacking real-time updates or detailed category selection that some alternatives offer. This can be problematic when driving through rural areas of the UK with patchy mobile data signal.
Furthermore, Google Maps can sometimes suffer from incomplete or inaccurate data, leading to incorrect routes or missing information about unusual road conditions like temporary closures due to local events or unexpected road damage. While it flags traffic, it may not re-route as proactively as some community-driven apps in response to sudden incidents. There are also ongoing discussions around data collection and privacy, which, while beneficial for improving the service, can be a concern for some users.
Given the occasional shortcomings of Google Maps, many UK taxi drivers and commuters are exploring alternative navigation apps. These alternatives often offer specialised features that cater to specific needs, from robust offline capabilities to enhanced public transport information or superior privacy controls. Here's a look at some of the best options available:
| App Name | Offline Maps | Real-time Traffic | UK Specifics | Cost | Key Advantage |
|---|---|---|---|---|---|
| MAPS.ME | Yes (Downloadable) | Limited | Good for rural areas | Free (with ads) | Extensive offline maps & travel guides |
| Waze | No | Excellent (Crowdsourced) | Great for avoiding jams | Free | Community-driven real-time alerts (police, hazards) |
| Citymapper | Limited | Public transport focused | Best for city public transport | Free (premium features paid) | Comprehensive multi-modal public transport planning |
| TomTom GO Navigation | Yes (Downloadable) | Excellent | Trusted UK mapping data | Subscription | Highly accurate traffic & lane guidance |

It's particularly useful for pinpointing exact locations in areas without traditional addresses or in large open spaces, making it a valuable supplementary tool for taxi drivers.
Q: Can I change the default start location in Google Maps?
A: Unfortunately, no. Google Maps is designed to automatically use your current location as the default starting point for directions. While you can manually input a different starting point for a specific journey, there isn't a setting to permanently change this default behaviour.
Q: Why does Google Maps sometimes give me the wrong route or miss road closures?
A: Google Maps relies on a vast database and real-time data, but sometimes information can be incomplete or outdated. Unexpected road closures due to local events, sudden construction, or weather damage might not be updated instantly. Additionally, complex road networks or remote areas can sometimes lead to less optimal routing. Apps like Waze, with their community-driven updates, often react faster to such dynamic road conditions.
Q: Are there any completely free alternatives to Google Maps that are good for UK driving?
A: Yes, many excellent alternatives offer robust free versions. Waze, MAPS.ME, HERE WeGo, and Citymapper (with some paid premium features) are all free to download and use, providing comprehensive navigation services that can rival or even surpass Google Maps in specific areas like real-time traffic alerts or public transport planning.
Q: Is Google Maps safe for my privacy?
A: Google Maps, like many Google services, collects data to improve its services and provide personalised experiences. While Google states this data is used responsibly, concerns about data collection and privacy are valid for some users. If privacy is a primary concern, alternatives like Magic Earth are specifically designed to operate without collecting any personal data or showing advertisements.
In conclusion, understanding why Google Maps displays the 'Preview' button is straightforward: it simply means you're not yet at the detected start of your journey. A quick check of your starting point and phone's location settings will usually resolve this. However, for UK taxi drivers and anyone regularly navigating Britain's diverse road network, exploring the rich landscape of alternative navigation apps can offer tailored benefits. From the crowdsourced alerts of Waze to the robust offline capabilities of MAPS.ME, or the privacy-focused approach of Magic Earth, there's a tool out there to perfectly match your navigational needs. Choose wisely, and enjoy a smoother, more efficient journey across the UK.
