Thank you Custom marine for going to extra mile to find a part on an old GPS of mine that had broken. I didn't want to throw it away but I couldn't find the part myself. Thank you so much, it works perfectly now. -Dennis F.

I DO NOT RECOMMEND EVER DOING ANY FORM OF BUSINESS WITH CUSTOM MARINE ELECTRONICS. My experience with Custom Marine Electronics has to be the worst experience with any business I have ever dealt with. I dropped off an inverter at their place in a secure location after hours. Well, their "secure" location was not very secure because they lost my inverter. I even asked multiple times, are you sure my inverter will be safe there, "yes I can assure you it will be fine". So now they have been trying to "figure something out" for the past 3 months. I call regularly and never get anywhere or even a callback. In the meantime of trying to deal with this dead-end road, all of my batteries in the van, which need the inverter to charge have gone bad because they can not charge properly.
