GO 730 map problem

I bought a GO 730 with Western Europe maps in July this year and all has been working fine.

I'm going on holiday to California at the start of September. I bought a Western US map from TomTom, which I downloaded to a new 4Gb SDHC using Home (Ver2). I also copied the OS to the SDHC card. Tom Tom allows me to switch maps but I get an error message ' you cannot use this map with device' I bought the Go 730 from Halfords and there is no product code or map code in the box, so I'm reluctant to try the clear flash tool (in case I need to recativate my device or Western Europe maps).

I've emailed TomTom support and I'm bracing myself for the response Crying or Very sad

Any ideas why the map won't work? I thought that I could simply use the SDHC card for additional maps.

Make a full backup of the device using Windows Explorer (see FAQ page numbers 1 then 14) which you can find by clicking Here - once you have a backup you can use the Clear Flash tool as you can always revert back to what you had before - Mike

Mike, thanks for the quick response. I took the advice of PGPWS and made an Explorer back up as soon as I bought the Go 730 (and subsequent back ups for each update). I've run the clear flash tool but its made no difference as regards the US map on the SDHC.

I have a feeling that I should have removed the Western Europe maps from the internal memory and downloaded the US map to that location. The US map is probably locked because it has been installed on another 'device'....the SDHC. I'll try replacing the Western Europe maps with the US maps on the internal mmeory to see if that 'unlocks' the map. Otherwise, I'm in the hands of Tom Tom support. Shocked

Try a pin reset on the 730 as well.

Hi
Just a note about canada & US mapping,When you get the mapping on your go you will not be able to see the maps or opperate the Tom Tom as there will be no satelites available untill you get to the otherside of the Atlantic.
Cheers

You only need the North America map folder on the SD card so get fid of everything else that is on the card, with the application files on the card the device will be trying to use these instead of whats on the device.

Your 730 can share memory locations between the internal Flash store and the SD/ SDHC card, so it doesn't need the application files on the card as well.

I would also try running the Clear Flash file three times as I have seen this mentioned previously, a number of times - Mike

Hi Everyone

Thanks for the replies and suggestions for sorting the problem with the US Map. The main reason for using the map while still in the uK was to set up an itinerary for our trip to California.

I've cleared everything off the SDHC card (except the map) and run the clear flash tool a few times. Still getting the error message. Could i delete the US map and let Home download it again or do I get one chance only for downloading a purchased map?

The main thing is the satnav is working fine on internal memory with the European maps and I'll keep the forum posted on my experiences with Tom Tom support.

If you remove the map from your device and from the downloads folder Home uses to store things on your computer then it will download a fresh copy of the North American map so its certainly worth a try.
The UK support phone number is 0845 161 0009 - Mike

Mike, Thanks.........it worked! Smile

I cleared the US map from the device and the download folder and then connected to Home, which downloaded the map again. All seems fine. Now I can start to plan my trip on Tyre (after I make an explorer backup of the US map).

Cheers

That's what I thought and sure enough, my position was 'off' the US map.

Just to let you all know that I have now used Tyre to plan my trip in the US. Great bit of software and very easy to use. The acid test wil be whether the TomTom behaves itself in the US and follows the route. All will be revealed in two weeks time. Cool

Be aware that with the functionality of IQ routing, your TT may indeed NOT be inclined to follow the Itinerary precisely that you set out using Tyre.

It may take you through the various waypoints but not necessarily using exactly the roads you selected.

The more waypoints (max is 48 per itineary) you put in your itinerary, the less chance for TT's routing algorithm to deviate from the way you want to travel.

Thanks for the useful tip. I'll check my waypoints.
