The suction cup mount can be used on a windshield or dash. It comes with a disc that has a 3m adhesive on one side and smooth on the other. You can attach the disc to a flat surface and then attach the suction cup to the disc. The suction cup on the LM-505 is made from polyurethane which is “sticky” in some cases in can be attached to the dash without using the disc.
This package comes with the EXP-2 HT face plate. This mount will work with any HT or portable as long as it has a belt clip. The face has a non skid silicone pad to protect your device.
