I have several questions, any help would be appreciated. 1) Will the Lowrance LGC 4000 GPS antenna work correctly with both a HDS 5 and a LCX-28C HD? 2) My new to me Cat has a wide angle transducer cable folded under the tolling motor panel on the bow. Is this pod positioned in the front of the hull bottom, or does it go all the way to the rear pod? 3) The current Lowrance 2000 GPS antenna appears to be riveted to the hull, from the bottom. Do I need to drill this out, or is there an easier way to remove this antenna? 4) Does the transducer switch available from Lowrance work with the HDS units? Any help would speed up this whole deal for me, and possibly save me some bucks too. Ive got to get my new cat right. My last Pantera was perfect, just a tad aged. Thanks Again, Allen
