Re: GPS Hook up to DSC Radio
Yes, you can do this. You don't mention what Garmin handheld you have, but I suspect you are inquiring about what is nearly identical to my set-up. I also have the Uniden Solara DSC and it is connected to a very old Garmin eTrex Venture. For reference, the Venture has a B&W screen in a green plastic case. To do this you will need a data cable. You can improvise with the cable that came with the GPS unit, or you can order a new cable. Garmin's website offers most cables, but you can sometimes get a better deal at Amazon or Ebay. The cable I ordered from Amazon had exposed wires to connect to the VHF radio along with a power plug. With this data cable I don't have to worry about batteries in the Garmin. Best thing I ever did. I think it is silly to own both a GPS and DSC VHF and not have them connected together.
