I also wanted to groan at simpa like papa goose but then I checked the price online. You can get it online for as low as 217 chf with free shipping.

Would you pay 160 for it with a map which is probably one year old? I am sure that the OP tried to offer a good price...actually for what he/she paid he/she offered a very good deal but unfortunately with electronics it does not always work...If it has free updates it is a good deal...if not...paying around 70 chf extra for better maps might be worth it...
now...if simpa did not have this in mind...he deserved the groan
