TomTom GO Classic 5-inch or 6-inch: which sat nav is the smarter buy?
If you’re choosing between these two TomTom GO Classic models, you’re really deciding whether to save money or pay extra for a bigger, more comfortable screen. Both are aimed at UK drivers who want reliable traffic info, speed camera alerts, EU maps and WiFi updates without the hassle of phone mounting. The key difference is simple: Product A is the cheaper 5-inch model, while Product B costs more but adds a larger 6-inch display and Moving Lane Guidance. Here’s which one makes more sense for real-world driving.
TomTom Car Sat Nav GO Classic, 5 Inch, with Traffic Congestion and Speed Cam Alert trial thanks to TomTom Traffic, EU Maps, Updates via WiFi, Integrated Reversible Mount
TomTom Car Sat Nav GO Classic 2nd (6 inch, with Traffic information, speed cam alert trial, Europe Map updates included, updates via WiFi, Moving Lane Guidance, integrated reversible mount)
Our Recommendation
Product B is the better overall buy because the larger 6-inch screen and Moving Lane Guidance make a real difference in everyday UK driving. It is easier to read at speed, simpler to follow in motorway traffic, and more reassuring at complex junctions. Although it costs £25 more, the usability upgrade is worth it for most drivers who want a more relaxed navigation experience.
Detailed Comparison
Display
Winner: Product B
The biggest practical difference is screen size. Product A uses a 5-inch display, while Product B steps up to 6 inches. That extra inch makes a noticeable difference when you’re checking junctions, motorway lane changes, or upcoming turns at a glance. On UK motorways, roundabouts, and busy urban roads, the larger screen is easier to read without squinting, especially if you’re sitting a little further from the unit or wearing glasses. If you do a lot of motorway or unfamiliar-road driving, Product B wins this category clearly.
Performance
Winner: Tie
Neither listing suggests a major difference in core navigation performance. Both models include traffic information via TomTom Traffic, speed camera alert trial, Europe maps, WiFi updates, and an integrated reversible mount. In practical terms, both should offer the same route calculation, live traffic rerouting, and map update convenience. For most drivers, the navigation experience will be very similar day to day. Product B does add Moving Lane Guidance, which improves confidence at complex junctions, but that is more of a feature advantage than a raw performance leap.
Build quality and design
Winner: Tie
Both units share TomTom’s familiar GO Classic design and an integrated reversible mount, which is a good feature for UK drivers who want a tidy dashboard setup and easy repositioning. The reversible mount is especially useful if you swap cars or want to move the sat nav between windscreen and dashboard positions. There’s no strong evidence from the listings that either model has a build-quality edge. The main design difference is the larger screen on Product B, which improves usability but doesn’t necessarily mean better materials or sturdier construction.
Battery life
Winner: Tie
Neither product listing provides a battery-life figure, and in this category that means there’s no reliable basis to separate them. Like most dedicated sat navs, both are best treated as in-car devices rather than battery-first gadgets. For UK motorists, that’s usually fine because the unit will be powered during journeys, and the important factor is stable operation, not all-day unplugged use. If battery life matters to you, neither model stands out from the information provided.
Price and value for money
Winner: Product A
Product A costs £114.99, while Product B is £139.99, a £25 difference. That is a meaningful saving for a sat nav that already includes the core features most drivers want: traffic info, speed camera alert trial, EU maps, WiFi updates and an integrated reversible mount. For many buyers, the 5-inch screen is perfectly adequate, and the lower price makes Product A the better value. If you want dependable TomTom navigation without paying extra for a bigger display, Product A is the smarter spend.
Features and usability
Winner: Product B
This is where Product B earns its extra cost. The standout addition is Moving Lane Guidance, which can be genuinely helpful on complex motorway interchanges, multi-lane roundabouts and unfamiliar junctions. For UK drivers who regularly tackle the M25, Birmingham ring roads, Manchester approaches or busy holiday routes, that extra lane clarity can reduce stress and last-second lane changes. Product A has the same core traffic and camera-alert package, but Product B feels more confidence-inspiring for high-pressure driving situations.
Overall user experience
Winner: Product B
In everyday use, Product B is the more comfortable and confidence-boosting sat nav because of the larger 6-inch screen and Moving Lane Guidance. Those features make navigation easier to follow quickly, which is especially useful in heavy traffic, poor weather, or on roads with complicated lane layouts. Product A still delivers the essentials very well, and it may actually be the better fit for drivers who want a compact, simpler unit. But if you want the nicer day-to-day experience, Product B has the edge.
Overall summary: Product A is the better value choice, but Product B is the better sat nav if you want easier readability and more advanced lane support. Both are solid TomTom options with traffic info, camera alerts, WiFi updates and EU maps, so you are not choosing between good and bad — you are choosing between value and convenience. If budget matters most, buy Product A. If you want the best all-round experience and can justify the extra £25, buy Product B.
