We love the HDS Carbon series. Lightweight, very clear screen, quick processing. If you are still using a phone or iPad for prerunning or trail runs, you are under-prepared.
HDS 7 Carbon is a great display very bright and shows a lot of detail , with mapping software and topo maps. I also have SiriusXM Satellite Weather and Radio Module it has very high resolution weather radar . When I'm out storm chasing or off roading I consider this must have safety Equipment. When I ordered this online , I got a call confirming some of the software I purchased and if it was compatible with some mapping software I had already had , great customer service .
