30 min to calculate 750 km itinerary?

If anyone experienced would care to comment:

after upgrading to TT Nav 5 version 5.2 yesterday the system takes a very long time to calculate itineraries.

- I'm new to this so may not be aware of what's 'normal' (no mention of this in manual etc.) but should it take 20 min+ to calculate a 750 km itinerary (Geneva to north of Cologne Germany). Takes forever - very slowly counting down the kilometers etc.

- Is there something I'm missing, some kind of setting?

thanks a lot

PS: my problem of hung PDA every time when deviating from calculated route, with version 5.04 of the software and Tungsten E2, disappeared after loading version 5.2

Try a different brand of SD card, this is having a big impact on calculation speed.

As a user of both TomTom 5 and Copilot 6, I have always been disappointed by the time TT 5 takes to calculate routes. Copilot will calculate a 400-mile route from South Lincolnshire to Aberdeen, UK in less than a second, while TT 5 takes almost 4 minutes with my existing hardware.

Lutz mentioned that a faster storage card should help. Does anyone know roughly how quickly TT 5 would calculate my 400-mile journey with the fastest cards, and what speed card would that be?

I just checked the time on my GO, and from the Centre of Spalding to the Centre of Aberdeen, 451 miles, took 12 secs.

I usually go for the High Speed SD Cards.

Thank you for your reply.

I have to confess to giving incomplete and rather misleading information. First, I didn't mention that I was working in Shortest routing. Second, I failed to mention that there was a toll charge in the shortest route, which I opted to avoid - thus effectively doubling the calculation time. Using Fastest routing, there was no toll charge and the calculation time was about 30 seconds.

This still probably represents the difference between an acceptable delay and an intolerable one under many circumstances, but I'd be grateful if you could say what the calculation time for yours is for Shortest routing.

When you say "faster" SD cards, could I ask what speed rating you actually mean, please.

I think mine are 60x or 66x.

Thank you for your trouble. When I find out what my various SD card's own ratings are (yes, I realise I should already know), I will be in a position to seek out some better ones.

Just one point if I may: I have been told that because the TomTom Go models run under a dedicated OS rather Windows CE or similar, they run TT 5 significantly faster than your average PPC. Do you, or others, know how much truth there is in this, please?

Thanks to Richard and Mullet.

All of this has led me to purchase Pocket Mechanic, a utility that tests for factors such as read and write speeds. It gives the Pure Media card that I use for TomTom 5 a benchmark of just under 5x. This is startlingly lowcompared with the 60x quoted by Richard and Mullet. Does anyone know if Pocket Mechanic gives a 60x benchmark to a 60x card or, does that also depend on the PPC used for the test, please?

PS The Pocket Mechanic benchmark I quote above for my Pure Media SD card is for reading, not writing.

I have now ordered a 60x card and am looking forward to seeing the results. I have also found the following thread:

http://www.pocketgpsworld.com/modules.php?name=Forums&file=viewtopic&t=23491&highlight=mechanic

Through that thread, Dunos has attempted to set up a database answering the sort questions about speed benchmarks that I have raised above.

Having said all this, Richard's (Oldie) results show that under some circumstances even a fast card and a TomTom Go unit will leave users twiddling their thumbs while the route is calculated.

Thanks again, Mullet. It sounds as if any gain I get is going to be pretty marginal. As you say, though, SD cards are useful to have.
