have a look, this is cheaper than me updating my maps on my old one !!



Note:   this is not an endorsement of this item, there are several makes that will do Lat/Long which you will need for the rally  

I have a Garmin Nuvi 255wt & a Garmin Nuvi 54 which both accept Long/Lat in the Rally format, only the Nuvi 54 has the 'lane assist' feature though. Both are very good units & are reasonably priced too, if I remember correctly, the 255wt cost me around £60 on ebay & the Nuvi 54 was £110 from Tescos.
