Hi, I've used the 338 which is very similar. Actually, I bought CoPilot which is great! Have used it locally and in several other cities. You can order the software from
www.buygpsnow.com either just the software or bundled with GPS. I have another phone I use it with and have a 2Gb memory card, but a 1Gb card would also work. You can just put a larger memory card in your Q phone, then store the CoPilot Live 6 maps and maybe program on it. You won't have to take anything in and out. That's only if you buy the card from ALK that has the maps and sw already on it. I loaded the sw on my laptop and then just transfer maps over when I travel.
I'd highly recommend the Globalsat Bluetooth GPS receivers and ALK CoPilot Live software. I understand the 359 receiver may be a little more sensitive and has slightly less run time than the 338, but they are the standard for GPS receivers.
