I believe Nav 6 maps will work on the 7, but not the opposite. Generally older maps work on new apps. Check with TT support to be sure.
Also search this forum - this has come up before.
Here is my entire exchange with Tom Tom support, they clearly state that the Navigator 6 maps won't work with Navigator 7. So, I gave up on Tom Tom yestday. I built a new ROM for my phone that doesn't waste the space for TomTom and will get buy with Google Maps.
If I do find a bootleg version of TomTom 6 and US maps I may try installing, but at this point, I doubt it. I guess I'm done with TomTom, lost customer...

Dear xxxx,
Navigator 6 maps will not work with Navigator 7. There are US cities available for the free city map that Navigator 7 users get, but no country or regional maps for North America compatible with Navigator 7.
With Best Regards,
Tom

But that can't be true. If you don't have any USA Maps for Navigator 7 how did you let me register the device and download a single city, Austin TX ?
Can you tell me if the Navigator 6 maps will work for the USA??

Oh yes.... and my frustration is further complicated by the fact your menu system for asking questions doesn't even include Navigator 7, hence this question was filed under Navigator 6.
I have attached a screen shot of your web site offering me maps for everywhere EXCEPT USA

I'm really frustrated, I've just been trying to buy online maps for the USA, or at least the SW USA and failed.
I have moved from the UK to Texas. I have a Vodaphone
I've spent 45-minutes download and installing the latest version of TomTom Home on my PC, that had me download an update to TomTom Navgator 7.9
After downloading, rebooting my phone, uninstalling the earlier version of my Storage card, installing the newer version, connect it to my PC and waiting for ToTom Home to start, which it does. It prompts me to select either the phone or the storage card(I've tried both).
I am able to do anything EXECEPT buy maps. I can download voices etc. but when I try to buy a map it gives me no choices to buy anything. The only map I have for the US is Austin, TX where I now live and that works fine.
When I go to the Map shop online via a web browser, it offers me maps for almost everywhere EXECEPT the USA.
PLEASE HELP! I am planning to go away on Tuesday and would rather use TomTom than Google Maps but can't if I can't buy it!
