Right, got a 'perfectly okay for my uses nuvi 200' that I've had for a few years... dont use it much, works..
But am going to america for 3weeks and will be driving A LOT, so .
1.. looked at updating maps, 60quid ( or50 or?) and even then, no guarantee it'll work on the nuvi because it's not got that much memory ( or is this bad online advice?)
2. rent one with the car..... HOW MUCH? basically more than a new device.
3. buy a new device in uk... so far, can only see one garmin , the 2475lt which is nice, but not every available and can't see it working because halfords (etc) dont bother stocking em.
4. buy a new device in US, cheaper, could just get an american only one..
5. opensource maps, so far havent managed to get these working, also not clear if they support routing and have POI
6. app for phone. could do, but not sure about phone in US ( thats another issue to check
)
any ideas, advice? maybe info about other brands?
thnx
oh and did have a look at a bike gps , figured nice excuse
, but they seem to be even more pricey
