Navigator 5 and GPS hardware

Thanks to everybody who gave such helpful information about the Navigator 5 upgrade and the way to get round the difficulty of not having enough temporary memory. It worked and I now have my maps installed and have activated them.

I now have another question. My pocket PC has asked me to specify the GPS hardware. It gives a selection of choices:

TomTom Cable GPs
Other Bluetooth GPS
Other cable NMEA GPS
TomTom Wireless GPS

My GPS receiver is an Arkon powered GPS mount.

Am I right in assuming that I should select 'Other cable NMEA GPS'?

Thanks
