A while back some body was looking for a Navionics Hotmaps card for Lowrance or HB unit. Cabales has the Premium 2010 reg $149 for $124 & the regular Navionics HotMaps 2010 reg,$124 for $119.00 with $5.00 shipping over $99.00 order. Now when u buy one of these new chips it will come with a prepaid mailer-enclose a older model Navionics card & mail to Nav & get $50.00 back. Net cost after shipping$79.00 on premium card. May save some one a few bucks. :D
