Greetings to All, I have a old Garmin Nuvi 360 unit and was looking around for a newer one. I noticed BestBuy got a Garmin 68LM for 9.99 cdn, so that is in my budget of around 0.00 for a unit. Reading some of the reviews I noticed some say that the internal memory size was insufficient. However I can't seem to find anything on the size of the memory. I am wondering if anyone here would know the internal memory size and why it would be a problem for some who bought this 68LM unit? Greatly appreciate any info on this. Cheers
