I don't think you'll find any other dedicated GPS units other than the Lowrance ones that will work with Mapyx Quo maps. Mapyx have partnered with Lowrance and I believe those devices are effectively running Quo Mobile software to handle the maps, so it's something of an exclusive tie-in. AFAIK the only other platform you can run Quo Mobile on is Windows Mobile, but that would mean having a Windows smartphone rather than a dedicated gps unit. (There is no Quo Mobile for Apple or Android, and no sign of anything under development).
I went for Quo on the PC when they launched in the UK and ran an older version of Quo Mobile on Windows Mobile v5 and v6 phones. The software was pretty good, but overall I preferred (still do) a dedicated gps unit rather than a smartphone. I now use a Garmin etrex 30, and just transfer routes, tracks and waypoints back and forward between that and Quo on the PC, but not the maps.
As to the Lowrance units, I don't know them, but one with the Mapyx tie-up was included in a gps review by Chris Townsend in TGO a year or so ago. It scored well and came out recommended - his only negative was the relatively small screen size. That's very much a matter of personal preference. Some people like a larger area visible, whereas the etrex has a pretty small screen but I find it more than adequate for the way I use a mapping gps.
Thanks Graham, good to meet you this evening, and nice to chat and see a little of your business too. Thanks very much for the fabrics. They were very well received when I got home with them (MoS is the one with the sewing skills), and they're going to be very useful.
Lightweight cordura - breathable, very durable - 2m olive, 10m royal
I'd happily take a trip out to Holywell if there's a suitable time this week. I'd be coming from Chester, and could possibly do Wed or Fri lunchtime, or else one evening straight after work - are any of those any good for you?
