Best pda for Tomtom 3?

I am looking to buy a PDA for use with Tomtom 3, Is there a best buy for this, I am considering the ipaq4700. Also can I use Tomtom with my lap top.
Also will a new purchase have updated roads such as the M6 toll.
And lastly I would like to be able to go from postcode to postcode are their any downloads for this?
Thanks.

Richard

I run iPAQ 4700 and TomTom, and I'm very pleased with it. For full postcode searches, you can use ukpostcode downloadable at http://www.digitools.co.uk/ukpostcode.php as TomTom limits you to just the first 4 characters. Other threads say the maps still don't show M6 Toll, though.

Oh well, I thought I may get more advice than nik96 but thanks for that anyway NIk.
I have gone for the bluetooth option I'll let you know how I get on. I take it coppied software is Illegal and frowned upon, is it worth paying for a Europe map to use once a year? any other recomended downloads?

Sorry you didn't get more input.

You should get the Major Roads of Europe on with the TomTom, but not the detailed towns without paying more. You're right: don't copy software - it is illegal. So, it depends what level of detail you want/need. If it's the annual holiday, you might be able to get directions for the final approach from the holiday operator - goes against the idea of a Nav system, I know, but it's a cost-effective compromise to navigate easily across Europe, and then use their paper map for that last bit...

You will need more storage for the maps: I got a 1GB SD card for about £50 so can hold maps, contact databases, music and there's even space if I want to buy some films to watch on train journeys.
